Heroic? Car bombings, suicide bombings and the like are not heroic at all, just as high altitude bombings are not heroic, but rather acts of murder.

I would disagree somewhat, especially with the suicide bomber example...

A suicide bomber believes with the utmost belief he is doing the right thing (assuming he's not a smart person who is purely driven by revenge, or just for the express ticket to heaven) he is someone who is literally willing to blow themselves apart to hurt the enemy...

Whether they go for what we consider a legitimate target or not if you are willing to lose or risk your life to fight for what you believe in you are a hero!

the high altitude bombers not so much (though there is obvisouly risk) but maybe more so the regular troops on the ground ect.

There are hero's on all sides in my eyes, just because they are doing the wrong thing doesn't make them any less heroic...
