This is revisionist tripe. The real reason we were slow to enter the war was that doing so was hugely unpopular among the two largest ethnicities in the US; Irish-Americans and German-Americans, for very obvious reasons. There were other reasons as well, but it's just a fact that Irish-Americans, many of whom would still have a living memory of the famine, were hostile towards the British, and German-speaking Americans, of whom there were millions, entire towns in fact, had no desire to go to war against Germany.

You leave this out because it's not convenient to your narrative.
