It's a very tough nut and there are no really good solutions, now that so many are here, on our soil. Any solution will be long in implementing and fraught with political skullduggery and calculation. They have us at our weakest point: Political correctness and "open" society. These are our flaws. This is why our offensive in their territory is so important. Cutting them off at the head will be an easier solution than weeding through the hundreds of thousands of individuals that may have infiltrated.
