Gallup: More Americans cite Iraq war as a mistake (63%) than Vietnam

Gallup:

The most recent USA Today/Gallup poll finds 63% of Americans saying the United States made a mistake in sending troops to Iraq, a new high mark by one percentage point.

The new high in Iraq war opposition is also notable because it is the highest "mistake" percentage Gallup has ever measured for an active war involving the United States — surpassing by two points the 61% who said the Vietnam War was a mistake in May 1971. At that time, however, Gallup found greater uncertainty (11% no opinion) and lower outright support for the Vietnam War (28% said it was not a mistake) than it does for the Iraq war today (36%), so it is not clear-cut as to which war was less popular with the American public.
