Probably because you keep neglecting to mention, for some strange reason, the ethnic group that made up some 90 percent of the population the peninsula at the time of the (not so peaceful) 1783 annexation. Let alone what, specifically, happened to them in the summer of '44.

And how obscenely ridiculous it is, as a result -- to say that the peninsula was "Russian for 200 years" prior to the 1955 transfer.

Except the US didn't just thumb their noses at, and start violating willy-nilly (like Russia did with the 1994 treaty you are so hesitant to name). Rather - it had an opt-out clause which Bush chose to enact, giving the required 6 months notice.
