Portuguese majority backs Russia dialogue as US emerges as Europe's second security threat

Erosion of transatlantic consensus within NATO; rising European strategic autonomy sentiment; generational divide with younger Europeans viewing US as primary threat; left-wing political movements leveraging anti-US sentiment; potential weakening of NATO cohesion as Trump administration policies alienate allies.

Similar to 1960s-70s European skepticism of US Cold War policies, when allied publics questioned American strategic decisions, though current context involves potential US withdrawal from traditional security commitments rather than aggressive interventionism.

Potential for reduced defense spending priorities, lower energy costs if Russia sanctions ease, but increased uncertainty around NATO commitments and transatlantic trade relationships could raise consumer prices and reduce investment confidence.

EU cohesion at risk if member states diverge on Russia engagement; potential sanctions relief negotiations; NATO burden-sharing disputes; possible trade friction with US administration; energy policy recalibration; defense procurement reassessment.
