That's what Islam means in Arabic, submission to God's will.
The God of Islam, referred to as Allah (meaning "the [male] god") in the Koran, evidently requires complete submission to every facet of life. A Muslim who no longer believes in the religion of Islam must be executed. Evidently an all powerful god is incapable of striking down the convert himself and needs humans to execute unbelievers for him. Why does God need a spaceship?
We stood by while they blew up those Buddhist statues before the war. We should move in and rescue this man if indeed they move to execute him. Give him religious asylum.
I cannot support continued involvement and investment in Afghanistan if their Constitution does not protect this man's religious freedom. If he is executed, I submit that we salt their poppy fields and leave them to their own devices.
