I understand and to some extent agree with your sentiment. I gather you are an American given this article is about an attack on U.S. troops. Assuming this is correct I venture to guess that you are a Christian. If so wouldn't it be more appropriate to pray for peace rather than just for troops from one country?
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!
