Oh yeah, banning religion will make everything ok. I guarantee you that this will start a third world war, and religion will win. These people will die for what they believe in, and the greater number, who do not believe that their purpose is here is to kill in the name of God, will recognize the threat as a legitimate reason to kill. You'll have a world wide genocide, one which you can't handle. A great number of American soldiers are religious, and if their right is threatened, they will kill for it, and kill those who threaten it.
If it was a joke, good, but if it wasn't you've got one of the worst ideas I've ever heard of.
On to Israel again. A military occupation to rebuild the government and put the people back in line, is the only solution I see. Its a long term solution, but its better than allowing more generations to grow up wanting to destroy a nation. The thing here is, religion should not be part of public education. Once this is removed, after a few years, while things are rebuilt and get better, things will change. Change will happen, through force. It takes time, guts, and a willing people.
Nothing to see here, move along.
