Germany's potential fiscal policy changes, which include increased defense spending and a significant infrastructure fund, are seen as a pivotal shift for the country's sluggish economy, according to analysts. Coalition negotiations are underway, and timely implementation of these reforms is critical for success.

Ursula von der Leyen, President of the European Commission, proposed a significant increase in defense spending through the 'ReArm Europe Plan', aiming to mobilize around $840 billion to enhance European security and support Ukraine amid ongoing threats.

European leaders are adjusting their strategies in response to Trump's harsh rhetoric towards Ukraine and his shift in U.S. foreign policy, indicating a need for more decisive action.

U.K. Prime Minister Keir Starmer is scheduled to visit the White House to strengthen U.K.-U.S. relations and discuss key issues including defense spending and negotiations around Ukraine.
