Ricky_Bobby: A really sad event, that people who make no harm whatsoever to society are not allowed to live peacefully.
Extremism and easy access to weapons can't be a good combination. Although that did not stop Anders Breivik.
If an extremist wants to kill people they'll probably find a way. Still, we shouldn't make it easy for them.
I think the best solution is for the West to attack ISIS and root out their network. Take away their credibility.
People do these attacks in the name of ISIS because it has become powerful enough for its followers to believe their ultimate goals are actually achievable. That's the extraordinarily delusional part of it. A new ISIS-like group will probably pop up, but we need to destroy them
before they get as large as ISIS,
before they gain credibility with potential followers. That's the reality we're stuck with.
The reality we're actually stuck with is that the West can't do this on its own. 99% of the victims of ISIS are muslims and 99% of the people actively fighting the organisation (rather than just talking tough on a forum or on a cable network talkshow) are muslims. That last part is particularly important. In order for ISIS to be defeated, WE NEED THEIR HELP.
Not all of the muslims standing against ISIS are what we would call liberal muslims. Many of them are fundamentalists who believe Sharia is the one true way to live, kind of like the radical evangelicals you see in the US think society should be ruled by biblical laws. Despite their radical beliefs, they abhor the idea of terrorist attacks and genocide. They'll still fight ISIS, just not to help the West.
If you're wondering why Bush (at first), Obama and Clinton won't say they're at war with radical islam, this is why. It's not about political correctness, it's about not insulting people whose help we need. There's a subtle difference between "radical islam" and "jihadi terrorism". The followers of the former are potentially reluctant allies against the latter. War makes strange bedfellows.
Being "politically incorrect" like Trump is is essentially saying the West can clean up this clusterfuck on its own. If you truly believe that, go ahead and insult the Islamic world as much as you like. Trump probably does think he can solve the whole mess himself, heck, he probably thinks he can solve it in person. He also thinks hispanics and women love him.
