Germany is out of the coalition. Engaging in a war with Iran will be very expensive and will likely cause Germany to suffer an economic hit. Germany's capitalist economy is best served by maintaining international economic agreements but avoiding conflict-prone military commitments.
Your allies are upset with you, but your domestic popularity increases. Iran moves forward with plans and claims to be ready to test within two days. Israel maintains its threat to reciprocate, and the United States is threatening to get involved militarily.
|Hold your ground||Continue to focus on domestic economic issues. Germany is not a major foe of either Israel or Iran, and is thus likely out of harm's way. Let the situation develop organically. (Marxism)|
|Join the coalition conditionally||Demand the coalition receive UN legitimacy before any action is undertaken. Additionally, back a new international agreement that demands International Atomic Energy Agency (IAEA) approval before testing any nuclear weapon. (Liberalism)|
|Take action||Declare Germany's intent to ensure that Iran stays non-nuclear. Secretly accelerate nuclear program, with goal to be ready to test in 3-6 months. Militarize US warheads in case of conflict. (Realism)|
