Germany has hugely increased its military spending, aiming to be less dependent on Washington. Its support for U.S. attacks on Iran may also give it leverage.

With American dealmakers wrapped up with Iran, neither Russia nor Ukraine has a clear path to victory — or toward a negotiated peace.

European Union nations have a little-known obligation to protect one another. Experts caution it is no replacement for NATO.

The United States views Iran through a prism of global responsibilities and strategic goals. Israel has a more regional approach. After nearly three weeks of war, their paths are diverging.

This time, President Trump went to war without preparing the public, seeking U.N. approval or even consulting allies. But they will have to pick up the pieces.

The Islamic Republic is aiming to draw out the conflict and broaden the fighting. That would force President Trump to risk more casualties and more political capital.

Soon the country’s armed forces budget could exceed those of Britain and France combined. In Paris, there are concerns that European “strategic autonomy” will have a German accent.
