Opinion of Adolf Hitler

[GMantis]

Hitler understood the threat of the Soviet Union, and had the guts to try to take it down.

Hitler did not regard the Soviet Union as a threat - he regarded as the place where he would expand Germany's living space.
If he was regarded it as a threat, he wouldn't have destroyed the country that blocked the way of the Soviet Union to central Europe, nor would he have allied with it against the west.
As for guts - Hitler totally underestimated the Soviet Union: "We have only to kick in the door and the whole rotten structure will come crashing down".

Hitler sought out living space for his people in order to increase Germany's prosperity and preserve fertility--the only biological reason we exist.

Germany today has a bigger population on a rather smaller area and yet it's much more prosperous today than it was then.
You should try to read a bit more real history and a bit less Stormfront.

Both, actually. It was a threat because it was the seat of Communists, who are by definition also Jewish; and of Jews, who are by definition also Communist.

But he didn't seem to have considered it much of a threat, considering how unprepared his army was for a long war.

A threat, but not in the conventional military sense. Does that sound right to you?

Certainly this was among the motivations for the invasion. But I think he would have wanted to destroy Russia even if it wasn't communist. Whether he would be able to find support in Germany for that is an interesting speculation.
