There are only two things we should fight for. One is the defense of our homes and the other is the Bill of Rights.
Okay, so this was written in 1933. The obvious question to me is, would the author have supported US involvement in World War 2?
I guess with Pearl Harbor, the US was attacked. But the Japanese at the time might have said that the US really started the war because the trade embargo on Japan was destroying Japan's economic plans.
So was World War 2 about protecting American homes? Or was it about enabling the US to enforce a trade embargo on Japan to reduce the size of the Japanese empire?
I am not a history expert and I don't claim that these questions have simple answers. I am just saying, I don't think there is any clear-cut answer of when a war is really for self-defense or not.
