Your words, not mine.

I did not infer even in the slightest that other countries participated in WW2 and helped to defeat the Nazis. But it is also fair to say, that it was America’s economic power even more than its military that was something the Germans simply had no response to.

I did not use the word, progressive to refer to a “conservative” …

Progressives and conservatives are opposites. They refer less to a philosophy than evolving ideologies.

Progressives advocate changes to the status quo to improve the human condition. They are not very concerned about the “how” but only the “outcome”.

Conservatives generally advocate the status quo for reasons ranging from different values to simply being happy with how things are.

I am a largely a classical liberal. In the past, I would have been called a “Kennedy liberal” today I am labeled conservative, but here is a decent definition of what I believe.

In my youth, the “progressive” movement was pretty much aligned with what I believed. But the progressive movement has abandoned classical liberalism in favor of socialism and to a lesser extent Marxism.

That is why “progressivism” is often referred to as an ideology based on the “greater good” and not a core set of beliefs and values. Today’s progressive movement to often stresses the rights of the majority to impose their values on the minority rather than protecting the rights of the individual including civil rights and property rights.
