What impact might the US policy shift have on America's European allies moving forward?

The US policy shift represents a traumatic change for European allies, particularly regarding Ukraine. Former German Ambassador Joachim Bitterlisch notes that Trump's approach may accept Russia's current territorial gains rather than pursuing the previously possible solution that would have maintained Ukraine's territorial integrity while establishing neutrality. This shift has emboldened Moscow, with Russian officials now feeling they're on equal footing with Washington again. European allies must now determine how to respond strategically, as the equilibrium between Russia and the US changes dramatically, potentially leaving Europe without American security guarantees for Ukraine.
