Do you think Muslims will dominate the world again like they used before?

I think many leaders in the West are in denial about the threats posed by massive immigration from Islamic countries.

Define mass. Are you even aware that in any given western country the percentage of muslims is between 3 to 5 percent tops? And here's another newsflash for you: Taking in refugees is not the same as immigration. One is controlled by international legislation, which also sets standards as to who's deserving of refugee status, the other one is entirely up to the particular state.
