I never claimed that Jews were the only religious group of people that was persecuted by the communists. Bolsheviks refuse to tolerate anything that is not Bolshevik, anyway, whether it is Jewish or not. But then I find it even more insane that some orthodox Serbs support Putin.
There is an important difference between persecuted Jews and persecuted Orthodox Christians in Russia, though : the persecution of Jews started long before the communists came to power, it was already virulent under the Czars, and often led by Orthodox priests and done in the name of Christianity, by the way.
As for America, I am certainly not so naive as to view the US as a systematic ally of Israel. The reality is much more complicated. First of all, America has been pressuring Israel to commit national suicide by giving her land to Arab Nazis for a very long time. That, to me, makes America an ennemy of Israel. Moreover, not only has America been selling all kinds of weapons to Arabs, but, even more seriously, America has saved the Arabs from a real military defeat on the ground every time the Israelis were in a position to crush the Arabs.
America, like every nation, pursues what it views as its own best interests.
Israel is fundamentally alone and should never rely on any outside help.
