Right...and you believe FDR should have sanctioned Stalin instead of allying with him.
We could have invaded Saudi Arabia after 9/11 instead of Iraq, but then there is that whole Mecca thing......which is kind of a complicated problem, I think you would agree. And, since they serve as a foil to Iran, it is an even more complicated problem.
They are a conundrum as far as US policy is concerned. They are an evil society...the radical Wahabian faith led to 9/11, and yet you want more Wahabians in the United States, while at the same time you want to punish the regime which regulates those Wahabians and cooperates with the US.
Evil preaches tolerance until it is dominant, then it tries to silence good.
