Easily, but with the kind of media coverage the US had in 1939, getting into the Iraq War in the first place might have been impossible.
Explain?
The US media would have been much more isolationist back then. Also, with much better contacts to Iraq's ruling clique. And there wouldn't have been any "embedded journalists" in the modern sense in the US army.
Bush would NOT have gotten the kind of free pass he was given to spread whatever false rumour he liked, which means he wouldn't have gotten congressional approval for his war at all. (Whether the media back then was *better* than now, is much more open to debate...)
