The IDF need to be rounded up and thrown in insane asylums. We need to have an island dedicated for this. It must be a desert island, no foliage (they can build a raft and escape)
no animals nor humans( they will be tortured) No communication. Just sand. No shelter. The island must be isolated enough no one can escape.
Food drops can be made every week, but not enough food. They can fight over the food. All food packaging must be made with very biodegradable material so no means of escape can be built.
A benevolent government will be in charge of policing this island so no one from outside is able to rescue them. The benevolent government will have the best satellites and hypersonic missiles.
