Trump Threatens NATO Withdrawal, Calls Alliance a Paper Tiger

President Trump said he is 'absolutely' considering withdrawing the US from NATO, calling the alliance a 'paper tiger' that failed to support Washington during the Iran conflict. In interviews with The Telegraph and Reuters, Trump stated NATO members 'haven't been friends when we needed them' and described the relationship as 'a one-way street.' A 2023 law co-authored by then-Senator Marco Rubio, now Secretary of State, requires Senate consent or an act of Congress for NATO withdrawal, creating a significant legal barrier. Bloomberg reported the threat is further complicated by Rubio's own legislative record.

Analysis
Trump's shift from 'considering' to 'absolutely' represents the most explicit US threat to NATO's existence since its founding. The 'paper tiger' framing is designed to undercut congressional defenders by redefining the alliance as a liability rather than a deterrent.
