I misspoke. I said sometimes you cannot avoid wars. You’re making shit up now.
War is 100% avoidable. It just matters what you are willing to give up. In that case, FDR chose to get us into World War II, pretty much against the will of the people, who looked at the waste of WWI and wanted nothing to do with another one.
It certainly wasn't about a telegram trying to get Mexico to attack us... that didn't happen in WWII like you said.
the last time I confused WWII and WWI was when I was five and trying to understand how Grandpa could have fought for Germany and Dad fought for America.... But I'm glad you are advancing past a five year old's understanding.
