@mizblueprint it's interesting to compare the Vietnam war at its least popular, when about sixty percent of Americans surveyed said that it was a mistake. Today, about 32% of Americans support the war in Gaza, so about 68% do not. The question is phrased differently, but the numbers are close.
@coldfish the polls are very different from what you're assuming. About 71% of Republicans support the war; about 8% of Democrats. 25% of independents.
