It still does not refute my statement. It is a historical fact. What you are picking on is how they lost. That is a separate issue. And by the way, no one is standing in line to invade Iran anyway. So all this hand ringing and should we, shouldn't we is a moot point.
I think you are missing some big facts of history. Those countries like Germany and Japan were not on the way down before the war. They fought USA and not just invaded! They almost beat the crap out of Russia. Japan had half the Asia and Oceania before USA invaded them. Because they had a robust scientific and technological infrastructure and powers to be reckoned already before the war. On the other hand, you see a country like Philippines being under US occupation after WWII and you and I know what Philippines look like even now!
So if Japan, Germany or even Italy had any progress afterward, it owes to their state pre-war and NOT because they were invaded by the USA. That is why I brought up those two examples.
If you have other ones in mind, say Korea, Singapore etc. You need to factor in cold war and also the fact that they were more or less liberated from Japanese forces by allies. They too had some infrastructure in place, especially Singapore as a special colony of British. So I am not sure if you were refering to those as well. But they are completely separate issue.
Anyhow, my examples stand for your logic, or better say falacy. Forgot what the falacy is called but it is very common falacy.
