Should we have stood by idly when Japan invaded the Phillipines? How about Guam? Hawaii?
Yes. The only reason we had been those places was due to our imperialistic venture called The Spanish-American War that was stoked by the Hearst newspaper organization in a manner that led to the term yellow journalism.
Pacifists like you lack common sense.
I lack a lot of other things, too but one thing is not an appreciation of history.
You don’t know real history. You know the Howard Zinn “People’s History of the U.S.” version of history. I see you’ve learned how to use the Marxist phrase “imperialistic”. An appreciation of history? You certainly have a Marxist appreciation of history. You think like a Marxist and repeat their jargon like an adolescent college student.
