Germany with its allies Japan and Italy were a threat to the US,
Iraq was a puny country with a small population and certainly less a threat than North Korea (that I observe we have technically been at war with since 1950). Invading Iraq was unjustified, the WMD's were fictitious, and Cheney lied like Hell and is STILL lying like Hell.
I really doubt that we would be speaking German or Japanese, even if they had won WWII, but WWII posed a threat to the US and Iraq did not.
The first time we attacked Iraq it was supposed to be the "Mother of all Wars". It was anything but. The second time, Iraq was far worse off, and yet Condi claimed they would nuke us, others said they would infect us with weaponized smallpox, anthrax and cholera, and they would gas out troops with mustard gas. It was all pure horseshit. I KNEW it was horseshit, because I lived in Mexico in the 1960's and the government there was deceitful and far better liars than Cheney, Rummy and Juniorbush.
You are incapable of recognizing horseshit even when buried in it up to the eyebrows.
