An ungrammatical slogan occasionally appearing on the
t-shirts or bumper stickers of those who can't handle concepts too big to fit on t-shirts or bumper stickers.
The correct form is "Whom would Jesus have bombed?"; since Jesus was a first-century Jewish nationalist, the most likely answer is, "The Roman Empire."
"Who would Jesus
bomb?" was undoubtedly inspired by "What would Jesus do?", a question
best answered by "We'll never know. Jesus wouldn't have gotten himself into the
mess you'
re in."
