By executive order, Presidents just can't just blow away the leader of a country. It has to be done in the context of war, not assassination.

They have to send their troops in to be killed off by the other guy's troops and so on.

Ever watch the old revolutionary war reenactments?

Two armies face each other. Everybody waits for the leaders to bring their sword down. One row on each side stands up to shoot and be shot at while another row squats down to get out of the way and reload.

Total stupidity and you cannot just shoot the commander of the other side and end it immediately. That would be counter to the rules of war. Thousands of foot soldiers have to die to see which general won.

I agree wars are stupid but I don't think they ever will go away.

Now if you read up on what Obama said, he was always for the war in Afghanistan but not for the war in Iraq.
