Apparently these guys deserved a hellfire up the ass...

That being said ..

You can't go around offing American Citizens all willy nllly.

BUT

Were these guys the main target of the attack or they just happened to be with a bad guy that "just needed killin" ? If these "americans" were collateral damage. I don't feel bad. Don't be hanging out with terrorists and you won't catch a hellfire up the ass.
