<h1>UK PM Starmer Balances EU and US Relations Amid Brexit, Trump's Policies, and NATO Discussions on Ukraine and Defense.</h1> British Prime Minister Keir Starmer is navigating complex diplomatic terrain as he seeks to strengthen ties with both the European Union (EU) and the United States under President Donald Trump. Starmer, attending an EU leaders' meeting in Brussels, aims to ease Brexit-related trade barriers without rejoining the EU's customs union or single market. He faces challenges due to Trump's protectionist trade policies and domestic political pressures from Brexit advocates. Starmer is also focusing on security cooperation and maintaining pressure on Russia regarding Ukraine. Additionally, he plans discussions with NATO's Secretary-General on defense spending and support for Ukraine amidst Trump's controversial stance on NATO commitments.
