Why is Europe more worried about Donald Trump than Vladimir Putin?

Europe is more concerned about Donald Trump than Vladimir Putin because European nations feel they've been sidelined in diplomatic discussions between the U.S. and Russia. As American and Russian diplomats met in Riyadh, this meeting caused significant unease across European capitals that feel excluded from crucial security discussions affecting their region. The anxiety stems from Washington's diplomatic moves, which Europeans perceive as potentially emboldening Moscow. European leaders worry that Trump's approach to Russia might undermine their security interests and NATO solidarity, leaving them vulnerable in regional power dynamics without adequate consultation or consideration.
