Comforting to know that only 200 million want to barbarically murder us.
There's a pretty wide range of anti western sentiment among those 200 million. The number that actually want to "barbarically murder us" is some fraction of that fraction. Still a tremendous number of people, no doubt; but your comment doesn't address how we should deal with them without turning a great many of the others against us.
Get them TFO of the West. Europe can start by deporting any/all immigrants who are from Muslim countries or countries hostile to Western ideals...
Europe and America can designate Islam "hate speech" and ban Islam/the Koran...deport Muslim immigrants...
So in other words, citizenship rights terminated based on nothing more than nation of origin and/or religion.
No due process. Matters not if they've been law abiding citizens for decades, they're history. With their property confiscated too, I'd imagine.
So we spit on the Constitution, out of fear and cowardice.
We already did that once, much to our shame.
Other than that, we just have to wait for the next attack..and the next...and the next and so on until we in the West have enough with it and take out the garbage in other ways...
Wow, you're really bucking for a religious war here, in which millions of innocents will die, which will create legions of new terrorists all over the globe. This just happens to be exactly what Al Qaeda and ISIS WANT us to do. But somehow you can't see that.
We all feel your rage, but in order to effectively address this threat that rage needs to be tempered by wisdom and foresight.
