I feel I should state that I'm an atheist who used to be a Christian (at least I proclaimed as much). I've noticed a tendency of American Christians to have a nationalist perspective rather than a global one. This has struck me as odd given the message of Christ.
At any rate, pray for our troops tho. And those of Iran too!
Though I agree with your point about praying for peace, I can't help feel that you're extrapolating too much based on your experiences.
