Well, first and foremost, there is a big difference between Germans, Japanese and Arabs. Totally different culture. Totally different circumstances.

Secondly, back during ww2 era, we had some decent leadership. Abysmal leadership from the current administration does cloud the issue.

Most importantly, if we were going to succeed, doing so in afghanistan first was far far more important than attempting to do so in Iraq.

So anyhow, bad parralel.
