How many will it rise to, in the next few years. Maybe we haven't seen anything yet. I don't believe European elites, will ever figure it out. That is why they need to be driven out on a rail. It is coming to America too.
It will continue unabated throughout Europe. The big ones will be the upcoming Carnivals before Lent, which for the muzzies will have the added thrill attacking and assaulting during a Christian event. There will always be some large scale event with gatherings at train stations, airports, inside stadiums, etc.
Soft targets made softer by the lack of will to honestly assess and confront the problem. The muzzies are in it for the end game. Question is are the Europeans and us ready?
