Tell me, did we or any other allied country ever go after Hitler per se? No, we fought the people of Germany (and the people who sided with him). We made a concerted effort to end the *war.* When the *people* and the *military* had been stressed more than enough by the war, the military leadership eventually turned against Hitler.
Actually, there were attempts on his life by Allied covert ops, but that's beside the point. You're comparing apples and oranges - on the one hand, a formidable military force; on the other, a militarily ineffective band of irregulars, whose bark is much worse than its bite. Just take 'em out, that's all. It doesn't require much strategy.

I'd like to know of any speech by any American or British leader at the time claiming that we were at war with the German "people". One does not make war on peoples, one makes war on armies - or, in cases when there's no actual army, on armed thugs and their leaders. It's about time Israel recognized such an obvious fact.
