国策

The game map, showing only countries with non-generic focus trees.

National focus trees serve as a replacement for the mixture of decisions and triggered events which directed countries in previous iterations of Hearts of Iron.

The focus trees allow the players (and the AI) to direct the development of their nation. Each country has a focus tree, representing a number of progression paths (branches) available to that nation. These paths may be based on actual historical situations or on alternative historical possibilities. The individual options can range from political, diplomatic and warfare-related focuses to more economic and research-related focuses.

Due to the semi-random nature of the AI it ensures that no two games will play out in precisely the same way. Players wishing to have a more historical-based campaign can choose to do so by ticking the Historical AI Focuses option on the country selection screen (map) just before the start of a new game. It is important to note, however, that player nations are not bound by this and as such their in-game actions can still force the AI to pick somewhat less than historical choices.

The seven great powers (and 波兰) have a unique national focus tree in the base game. Additional countries - as detailed below - received a unique focus tree as part of different DLCs. All other nations use the generic national focus tree.

Mechanic overview

The Generic national focus tree has 5 different branches.

Branches in a focus tree revolve around a common theme or goal with the individual focuses within intended to help in achieving that goal. Although branches are mostly isolated from each other, they will be connected (locally) if they happen to coincide over a common point.

Only a single focus can be taken at a time. A focus requires 70 Political power to complete at a progress rate of –1 Political power per day - this means a focus would usually be completed within 70 days. When completed, the player may go up to 10 days without picking a new focus and still have those days (and their accumulated Political power) count towards the new focus.

Aside from the branches' top level focuses, most other focuses have additional requirements in need of fulfillment before they can be picked. If a requirement of an on-going focus has become invalidated, the focus will either be paused until the requirement is restored (if possible) or outright be cancelled when such a thing is not easily possible. For cases such as the latter, focuses will have bypass conditions to allow the player to proceed past them - the player will be notified of the bypass within a few days (they will display a golden bracket as if completed regularly). For example, Motorization Effort can be bypassed if the Motorized Infantry technology has already been researched beforehand.

Once a focus has started, the player can't manually stop or replace it, unless the player has the Man the Guns expansion. If, due to circumstances, the focus has been invalidated, the resources already spent are lost. As such, it is immensely recommended to check all requirements and conditions regarding a focus to assess if/how they may be affected within its completion time-frame.

Accessing a focus' expanded details can be achieved by clicking or hovering over the focus. Among the information presented there are: the flavor description, its requirements, bypass conditions (if applicable) and the expected completion effects.

Visual indicators

• Bracket color - Players can check at a glance a focus' completion status by the background color of its name bracket. Grey bracket means available for picking, brown bracket indicates as of yet unavailability and golden bracket denotes completed focuses. On-going focuses will feature a shining overlay effect over them.

• Connection lines - Focuses are connected by colored lines. The color indicates whether its preceding focus is completed (green) or not (light-blue). The connection may also appear as a solid or dotted line, with the former indicating a logical AND and the latter a logical OR. For example, to pick Special Forces would require all 3 of the focuses preceding it while picking Technology Sharing requires only one of the 2 preceding it.

• Mutually exclusive - Some focuses may have the mutually exclusive icon appearing in-between them. The icon denotes that only one of two may be selected. Further more, depending on the focuses outgoing connections it may also exclude from picking any of the focuses connected to them further down the line. For example, choosing between Collectivist Ethos or Liberty Ethos will make any of the other side's subsequent connected focuses unavailable for picking up until Technology Sharing (linked to both sides by an OR connection).

持续性国策是一种特殊的国策，你只有在至少完成了十个一般国策之后才能解锁使用。目前，游戏中一共有九个可用的持续性国策。

使用一个的持续性国策是以持续使用一个固定的国策为代价的，一般国策无法同时使用。因为无论其类型如何，一次只能有一个国策被使用。

与提供一次性效果的一般国策不同，持续性国策是在选中期间持续对国家发挥作用的。维持国策需要每天 –1 的成本。但是，国策可以在任何时候停用或切换到另一个国策而不需要任何的额外成本。（注意：一般国策在停用或切换后，已完成的进度不会被保存或继承。）

France

If 法国 capitulates to the 德意志国, it will be divided into 自由法国 and 维希法国, with both regimes receiving a unique national focus tree as part of the La Résistance expansion. Without the expansion, 自由法国 retains the French national focus tree, whereas 维希法国 utilizes the Generic national focus tree instead.

Free France

主条目：Free French national focus tree

荒谬的拒绝线

这条线着重于培养法国占领区的抵抗，并增加占领者获得顺从的难度。

号召法兰西线

这条线着重于恢复一定程度的战争能力，并与维希法国争夺对法国海外领土的控制权，以便为最终光复法国奠定基础。

Vichy France

主条目：Vichy French national focus tree

维希法国的独特国策树拥有一条主线

授予贝当紧急权力线

主条目：Warlords national focus tree

The Chinese warlords ( 滇系, 新疆, 桂系, 晋系, and 西北三马) share a unique national focus tree in the Waking the Tiger DLC. Without the expansion the warlords use the Generic national focus tree instead.

军阀的国策树可被划分为两个大分支和三个子分支：

稳定内政线

此条分支将为军阀解锁政治类国策。

亲国民党支线

此支线将允许军阀倒向 中华民国。这将会使Chinese national focus tree取代当前的通用国策树。

亲共产党支线

此支线将允许军阀倒向 中共且能够在 苏维埃联盟的支持下将中共取而代之。当取代 中共后，当前的通用国策树将会变为Communist Chinese national focus tree，并且你会拥有他们原有的民族精神。

冲突对抗支线

此支线将允许军阀对其他势力挑起边境冲突，倒向日本人一边并公开声明建立一个与 中华民国和 中共相抗衡的政府。

工业发展线

此条分支是国策树的工业发展线。

La Résistance trees

Spain

Spanish national focus tree.

西班牙 gets a unique national focus tree with the La Résistance expansion, which will be split into two separate trees once the Spanish Civil War breaks out. Without the expansion, it utilizes the Generic national focus tree instead.

Nationalist Spain

主条目：Nationalist Spanish national focus tree

The Nationalist Spanish national focus tree can be divided into 11 sections. 1 pre civil war branch leading into 3 main branches and 2 shared branches. A post civil war sub-branch can be split from each of these Branches:

大西班牙国分支

This pre Spanish Civil War branch gives Spain popularity to the 法西斯主义 and 中立主义 parties, 政治点数, garrison control over various Spanish states, and various divisions during the Spanish Civil War. Unlike the 西班牙共和国 Republican Spanish national focus tree, these focuses take 28 or 35 days rather than 70 days.

没有结果The Phalanx Ascendant Branch

This branch allows the 没有结果 to take power, increase 稳定度, create minor uprisings against 西班牙共和国, gain a research slot and gain Civilian and Military factories. This path will force the 卡洛斯派西班牙 to declare war making another faction to fight against in the civil war.

The National-Syndicalist State Sub-branch

Once the Spanish Civil War is over, this sub-branch allows 没有结果 to expand its navy, gain a research slot, gain factories and give army bonuses in recruitable population and training time. It recreates the Spanish Empire with war goals against 葡萄牙 and its colonies, 联合王国, 法国, 意大利, The 美利坚合众国, former Spanish Colonies and 巴西.

没有结果 西班牙国The Corpo Truppe Volontarie/The Condor Legion Branch

This branch is shared between the 没有结果 and the 西班牙国. It allows 意大利 and 德意志国 to send more volunteers to aid in the civil war. It also gives forts on the 法国 border, stability, political power and research bonuses.

The National And Popular Army of Spain/Join the Axis/National Recovery sub-branch

Once the Spanish Civil War is over, it gives the 没有结果 and the 西班牙国 research bonuses for the army, factories, infrastructure, reduces the effects of the "Recovering From Civil War" national spirit and gives national recovery bonuses.

西班牙国Unify the Nationalist Front Branch

This branch focuses on aligning the Falangist and Carlist factions under the leadership of Francisco Franco as 西班牙国. It gives stability and war support, and combat bonuses. It will also bypass an impending 卡洛斯派西班牙 revolt. There is also a focus that allows 葡萄牙 to send more volunteers which leads to two focuses that can only be done once the Spanish Civil War is over. These two focuses allow Spain to ally 葡萄牙 and create the Latin Bloc which also allies with 维希法国, 意大利 and other Iberian countries if they are available.

Join the Allies/Adopt the 26 Points Sub-branch

Once the Spanish Civil War is over, it allows 西班牙国 to join the 联合王国 or 美利坚合众国 faction, which gives naval bonuses, factories, boosts national recovery and removes the "Recovering From Civil War" national spirit. It adds a research slot. The Adopt the 26 Points sub-branch leads to a section that is shared with 卡洛斯派西班牙. The 西班牙国 exclusive section allows Francisco Franco to become dictator for life and leads to focuses that allows the sending of volunteers and wargoals against 法国 and the 联合王国.

西班牙国 卡洛斯派西班牙Utilize the Intellectuals Branch

This branch is shared between the 西班牙国 and the 卡洛斯派西班牙. It gives a research slot.

Restore the Monarchy Sub-branch

These focuses can only be selected after the Spanish Civil War is over. If the 西班牙国 take this branch, Alfonso XIII becomes leader of the 中立主义 party. If the 卡洛斯派西班牙 take this branch, it fulfills the choice made in the Settle the Succession Question focus and creates the Kingdom of Spain. Jaime IV replaces Alfonso XIII if the focus is not taken by February 28, 1941. The rest of the branch gives air buildings and forts on naval bases. These focuses must be taken by 西班牙国 in order to unlock the wargoal for Gibraltar and West Africa. 卡洛斯派西班牙 cannot take the focuses following these.

卡洛斯派西班牙Supremacy of the Communion Branch

This branch allows the 卡洛斯派西班牙 to prepare insurrections in the civil war, gain army bonuses, gain air and army research bonuses and civilian factories. This path will force the 没有结果 to declare war making another faction to fight against in the civil war.

Settle the Succession Question Sub-branch

After the Spanish Civil War, this sub-branch allows 卡洛斯派西班牙 to chose between Alfonso XIII or Javier I as King of Spain. Jaime IV replaces Alfonso XIII if the focus is not taken by February 28, 1941. It also gives naval research bonuses, a research slot and war goals against the 联合王国, the 荷兰, 比利时, 卢森堡, the 美利坚合众国, 古巴 and the 菲律宾. If France has Alphonse I as King, they may decide to become a Spanish Puppet. Otherwise, Spain gets a wargoal. 葡萄牙 may also chose to be annexed and cored by Spain or give wargoals.

Republican Spain

主条目：Republican Spanish national focus tree

西班牙共和国国国策树较为复杂，可分为12个区域，一条战前准备线导向3条主线和2个共享分支。主线和分支由内战前和内战后两部分组成，其中战后共产主义分支也亦有两种走向。

战前准备线：人民阵线

该分支在战前帮助西班牙共和建立对 西班牙国的军事优势。相较于 西班牙国的战前准备，这些国策耗时相对较长，所以玩家需尽可能延缓内战爆发直至所有国策完成（最后一个国策的完成将直接导致内战）。

阿拉贡地区防御委员会（Regional Defense Council of Aragon）线

国策树的 无政府主义线。该线可以激活增益性的 无政府主义社会民族精神和独特的 集体化社会经济法案和“委员会”政治顾问。这个分支也会在 葡萄牙触发事件，或许会导致它被西班牙吞并，爆发使西班牙核心化葡萄牙所有核心领土的安那其起义。

• 明日火炬手分支

当西班牙内战结束时， 阿拉贡地区防御委员会将着力于重振经济，并为即将到来的战争做好充足准备。这个分支会给予减少正当化战争目标时间的修正和在外国发动安那其主义革命的决策，并允许核心化高顺从度地区。

国际纵队/夺取黄金储备分支

这一分支由阿拉贡地区防御委员会和没有结果共享。它允许在内战期间每周增加人力，没收黄金储备以增加可用工厂，提振工厂产出，并将导致在内战中共产主义者（斯大林主义者）发动对无政府主义/反斯大林社会主义的镇压。

• 协力重建分支

当西班牙内战结束时，西班牙可以使用 协力重建 国策以进入战后分支。该分支的另外两个国策可以给予海军增益。

反法西斯工人革命线

共产主义国策树的分为两个部分。独立的革命路线允许建立一个反对 苏维埃联盟 的共产主义联盟，并建立 没有结果。这使我们能够采取与 没有结果和人尽其才分支共同的国策。斯大林主义的道路允许与 苏维埃联盟结盟（指变成苏联的傀儡），并建立 西班牙共和国。这将启用 西班牙共和国和西方的红色堡垒分支共享的国策。两条国策线共享一个增益工业小支。如果 西班牙共和国采取 Increase Arms Production可能会被 西班牙共和国占据

• 人尽其才分支

这个内战后的分支将帮助 西班牙公社从西班牙内战中恢复，与除亚洲之外的 共产主义国家结盟，并获得针对所有欧洲 法西斯主义国家、 墨西哥和 苏维埃联盟的战争目标。

• 西方的红色堡垒分支

This post civil war sub-branch allows 没有结果 to try to increase its autonomy if it is a puppet of the 苏维埃联盟, gain war goals on 葡萄牙, 法国 and all other nations who sent volunteers to the 西班牙国 side. This sub-branch is also shared with 西班牙共和国 if they take the Communists in the Government focus and may be done before the civil war is over this way.

Strengthen the Euzko Gudarostea Branch

这条线由 共产主义者与 共和主义者共享。这条线将寻求 苏维埃联盟在内战中给予帮助，作为回报，战后西班牙将成为苏联傀儡。这条线也会将激发 阿拉贡地区防御委员会成为内战第三方。

• 苏联重建援助分支

This post civil war sub-branch further increases military development if the Spain is still in a faction with the 苏维埃联盟.

保卫第二共和国线

这个民主主义分支允许 西班牙共和国提高自身稳定度和军事实力，同时也可以 法国求援。 西班牙共和国同时可以通过进行国策 反对共产主义者以从 苏维埃联盟的压迫下谋求自身独立并维护自身的民主主义制度。当然，西班牙也可以通过进行国策 政府中的共产党人以过渡至共产主义并进行 增加武器生产和西方的红色堡垒分支国策线中的 共产主义分支。

• 摆脱苏联控制/稳定国家/恢复高等教育分支

This post civil war branch allows 西班牙共和国 to declare war for independence against the 苏维埃联盟 with the aid of either the 民主主义 nations or 德意志国 and 意大利. It also increases military capability and allows Spain to join in the war against the 法西斯主义 majors.
