I don't know - I just don't like the idea of killing (or making life worse for) Christian minorities and those who protect them in the Middle East, which seems to be the crux of our foreign policy there for a long long time. Seems just about every place we get involved in the ME, the native Christian minorities suffer and the Muslim radicals flourish, add to that our effective contribution to the ethnic cleansing of Serbs in Kosovo and I sometimes wonder if my time in service was for any good.
Now - I'm not naive. As long as those mummified corpses of Lenin and his heirs lay in state in Red Square and not at the bottom of a cesspit where they belong, I will never fully buy Putin's claim that he is the protector of Christianity, but frankly his track record is better than ours.
Now if you aren't a Christian and have no particular care either way - this all just one Machiavellian continuation of the "Great Game," but as someone who does deep down think there may be something to that dusty old book, I really have to wonder what God we are serving these days......
