Weapons and military tactics will not win this war. The only things that you can send to Afghanistan to win this war are Missionaries. When the West is serious about endings its 15 century war with Islam we will admit we are fighting a war with Islam. You must give these people a reason to question and change their core beliefs and killing them doesn’t do it that well or at all. They need something to believe in that gives them a purpose that is not contrary to Western civilization.
Ok, if this is what they want, then this is what they're gonna get.
IMHO, God’s Providence is the solution, but there are other enemies within our midst who are enemies of Christ first and are seeking to use Islam as a tool to maneuver and promote all things antiChristian.
In the immediate situation while we are in country, murder (and all felonious acts) must simply be met by immediate capital punishment under martial law.
You are a real thinker, and believer. Send in the missionaries with plenty of Military guards, and make them listen. The Word of God will do the rest. We should also show them what love is. Jesus did say love your enemies. Love breaks down every barrier. Love and The Word of God are the two most powerful things on earth, not bullets and bombs. The war would be over and the people would be set free. There may be some casualties when armed enemies break through, but those believers that die would be ushered into heaven with crowns.
