It’s plenty articulate but wrong on both accounts. It’s hypocrisy to criticize (wrongly in OPs case) the US for not involving themselves fast enough in one breath and then criticize the US for being “world police” in the next.

Especially considering what the landscape might have looked like had the US remained on its isolationist track and not joined the war.

As for articulating why, with what they knew in 1939, the US should have declared war; you typed a lot but failed at the task. You say fascism like it carried the weight in 1939 that it does today. Fascism rose to prominence in early-20th-century Europe. Hmm, wonder who that was.

Swing and a miss!
