Rep. Don Bacon (R-Neb.) warned Tuesday that a potential U.S. withdrawal from NATO would create significant divisions within the Republican Party. Speaking to CNN, Bacon stated that such a move would result in "a civil war in the Republican caucus."

The Nebraska congressman's comments come amid ongoing discussions about NATO's strategic positioning and defense capabilities. Bacon indicated that most Republican lawmakers would oppose breaking up the alliance, suggesting broad support for maintaining the transatlantic partnership within the party.

NATO has been a cornerstone of Western defense policy since its establishment in 1949, with the alliance currently comprising 31 member nations. The organization has faced various challenges in recent years, including debates over defense spending commitments and strategic priorities.

Bacon's warning highlights potential fault lines within the Republican Party regarding foreign policy and international alliances. The congressman's remarks suggest that any proposal to withdraw from NATO would face substantial resistance from within Republican ranks in Congress.
