I suggest you look at all the desecrated and destroyed churches and all the other devastation being caused by the invaders; then tell me it's worth risking another war.
How many churches have been desecrated by Muslims?
How many have been desecrated by angry yoots with names like Fritz and Giorgio?
Europe, like its little brother on this side of the ocean, has a problem.
But it isn't Muslims, in the same way as our problem isn't Mexicans (or Chinese, or whoever's the next vote-generating scapegoat).
War and conquest can't be prevented now thanks to the EU and the invasion.
The fear of Muslims conquering Europe stopped making sense when Vienna didn't fall.
Again, the rot is coming from within.
Rome wasn't conquered by barbarians; it disintegrated, dissolved, one day stopped giving orders.
That's what will happen the day after the next and last European war ends, if that's allowed to occur.
It's not the fault of those who will fight to preserve what can be preserved.
There's a reason that people like Otto von Habsburg, who knew something of multi-ethnic states, spent their lives promoting the EU. They had lived through two wars, which ended the world, twice. It's impossible to overstate the difference between the world in 1914 and in 1945. People who saw this happen fought desperately to make sure that what could be preserved, what had not already been destroyed, would be preserved, and that it would never happen again. Europe is a single civilization, and it should never be divided again.
