Quick search, the US and the UK have roughly the amount of Muslims (4mil) and think more of those are recent immigrants to the UK. But UK has 20% of the population, and is about halfthe size of California. We can absorb, of course we shouldn't, way more and not feel the impacts outside of certain urban areas like Deerborn and Minneapolis. This doesn't take into account indians and other highly represented places of originIf accurate I could see this being the spark for WW3 in the future if it hasn't happened by then.
