“America paid an enormous price for their isolationism, it was called World War II. Isolationism caused that war”

You must have never studied history. It was our ill-advised entry into WW I that caused WW II. Hitler would never have risen if the Kaiser had not been unwisely deposed.

[Sudetenland]

You must not know anything about Neville Chamberlain and his "Peace for our times." Hitler could have been stopped any number of times quite simply and relatively bloodlessly if anyone had been willing to step in and stop him.

It was because the French weren't willing to confront him when he moved on the Rhine, that he was able to occupy the Rhineland. It was because Neville Chamberlain was convinced that diplomacy could convince Hitler to behave that he was able to occupy the Sudetenland.

It is clear that you have not spent anytime studying history if you believe it was because of what America did in WWI that caused WWII. The presence of absence of America had little bearing on the roots of WWII beyond assuring an allied victory.

America WAS isolationist during WWI--and in the beginning of WWII. We entered WWI because Germany was threatening to conquer Europe and isolate our ally, Britain. We also entered WWI because the Lusitania was sunk by the Germans, an unprovoked attack.

There are many causes of WWII, but there would have been no actual war had the allies not been so dedicated to "non-intervention." The rise of Hitler, or someone like him, was inevitable, but actual war could and would have been stopped had someone bothered to actually oppose him.

What Paul and apparently you fail to understand is that aggressive powers do not leave you alone if you ignore them. They see that as a sign of weakness. They see appeasement and negotiation as signs of weakness--they see diplomacy as a sign of weakness. They will invariably seek to exploit that sign of weakness--that is what causes wars. Peace through strength isn't simply a catchy motto, it is a hard learned lesson of history.
