96% of the UK is NOT Muslim. The UK Muslim birth rate is/will be dropping. For all the noise, Muslims don’t have any major political, social or economic power.
Does the UK have a Muslim problem?. Very much so, and one we have been and need to sort out, but ideas of a conquest are nonsense.
For one thing Europe in general seems to be moving in an antisemitic direction.
For another the blitz of Muslim immigration does not depend on birthrates. All of Europe is likely to be inundated.
