An army is not defined as a bunch of uniforms.
An army is defined as being a large group of people able and willing to use violence to accomplish a political objective.
Our opponents are an army, the Army of Islam. We are in a war. It doesn't matter to them if we refuse to realize it.
You misunderstand me.
When you fight an army, you don’t kill prisoners. You send statesmen to seek a peace. And you are bound by international law. You recognize you will likely have to kill or be killed, but you can also respect that the individuals you fight are fighting for their families, their nation and their honor, no matter how vile their leaders’ politics are.
When you fight terrorists, you execute prisoners as criminals. You fight until their utter destruction, with no negotiation. And you are a God-damned fool if you restrain yourself by international laws which you know they will not respect. You owe them not one stitch of respect, and when you kill them, you know their widows and children should rejoice with you.
