This is our future, FOREVER, unless we stop Muslim immigration and initiate a steady out-migration of Muslims from the West until their remaining numbers are a small fraction of what they are now and there are no true believers among the ones that remain. Travelers from Muslim countries must be tightly restricted as well. Muslims must be essentially locked up inside the Muslim lands, with only carefully screened individuals allowed into the non-Muslim world.
The enemy are among us, in America, in Britain, in the West, and will remain so until we remove them from the West and indeed from the entire non-Muslim world. As extreme as this sounds, it is a no-brainer. There is no other solution. All other responses to this problem add up to meaningless hand-wringing. The hand-wringing will go on FOREVER, along with the terrorist attacks and the threat of terrorist attacks, until we take the ONLY STEPS that can actually and permanently end the threat.
The strategy ISIS and other orthodox Muslims are now following was laid out by by the late Sheikh Abu-Bakr Naji. His big insight was this: It is impossible now to achieve Islam's prime directive the traditional way, which was to invade countries and establish Islamic law by force. This method may have worked fine when non-Muslim countries were unconcerned with things happening in other parts of the world. Back in those days, using the traditional method, Islam successfully established most of the now-existing 56 Muslim countries. But these days non-Muslim countries are too powerful militarily and would stop it.
So in 2005, Naji proposed a new strategy: He said the way to ultimately accomplish the prime directive is to fight the entire non-Muslim world everywhere at once, and to create an increasing occurrence of ever-more-violent events so non-Muslims everywhere would feel insecure and would eventually live in constant fear of violent death. They would lose trust in their government's ability to protect them. They would become exhausted from insecurity and fear, and would then be willing to embrace Islamic rule just to make the violence stop and to be able to live in some sort of peace...
