MA 2 – President Simulator: How to Sign Mutual Defense Pacts

To sign a mutual defense pact in MA 2 – President Simulator, open the Ministry of Foreign Affairs, select your target ally, and fulfill three sequential diplomatic requirements: build an embassy, raise bilateral relations to at least +60, and ratify a non-aggression pact. Once active, the treaty commits your ally to join your defense if another nation attacks, raising your deterrence rating against aggressive neighbors.

Diplomatic Prerequisites and Signing Order

You cannot propose a defense treaty immediately. The game requires progressive diplomatic agreements to establish trust before unlocking military alignment.

Build an Embassy: Open the target country's profile in the foreign affairs menu and fund an embassy. Constructing this facility establishes continuous communication and unlocks higher-tier treaty options.
Elevate Bilateral Relations: Increase your standing to between +60 and +80. Send regular cash gifts from your national treasury, sign trade agreements, or establish cultural ties to raise relations without triggering domestic unrest.
Ratify a Non-Aggression Pact: Secure this treaty first. Target nations reject mutual defense proposals if a baseline non-aggression agreement is not already in place.
Sign the Mutual Defense Pact: Once relations reach the required threshold and peace is formalized, propose the defense treaty through the diplomacy menu.

Agreement Type	Required Relation Level	Primary Strategic Effect	Inherent Risk Factor
Non-Aggression Pact	+20 to +40	Prevents direct conflict between signatories	Low; limited to bilateral peace
Bilateral Trade Pact	+30 to +50	Exchanges surplus resources and builds trust	Low; creates trade dependency
Mutual Defense Pact	+60 to +80	Obligates military assistance during invasions	High; risks wartime entanglement
Military Base Treaty	+80 to +100	Grants troop stationing and passage rights	Moderate; escalates border friction

Deterrence and Combat Mechanics

The primary benefit of a mutual defense pact is invasion prevention. The game's military AI tallies your standing divisions alongside the military power of all active defense partners before declaring war. Aligning with a heavily armed superpower artificially inflates your defensive strength rating, deterring hostile neighbors from starting border conflicts.

If an enemy nation declares war despite your alliance, the treaty triggers automatically:

Allied Co-Belligerence: Your partner enters the war immediately without requiring additional diplomatic prompts or payments.
Divided Hostile Forces: The invading nation must divert ground forces, armored divisions, and anti-air assets across multiple borders instead of focusing solely on your territory.
Resource Conservation: Allied air wings and naval fleets engage enemy infrastructure, allowing you to hold fortified chokepoints and conserve domestic manpower and budget reserves.

Treaty Maintenance and Strategic Risks

Defense treaties are strictly reciprocal and carry operational liabilities that require ongoing management:

Mandatory Call to Arms: If a third party attacks your ally, your nation is obligated to enter the war. Refusing the call dissolves the agreement, inflicts severe negative relation penalties, and degrades your global standing.
Treaty Expiration: Pacts lapse over time and require renewal. Keep bilateral relations comfortably above +60 through recurring trade deals and foreign aid; if geopolitical friction or United Nations votes depress relations below the threshold, your ally will refuse to renew the agreement.
