Edit: It is hilarious to me how the leftist are trembling about Putin, Trump, Le Pen and so on. What you guys don't get is that you are witnessing a massive, popular shift to the right throughout the West with a right wing ideology that is indeed partly influenced by Putin. Why? Because it is successful. This doesn't mean that they are controlled by Putin, they just share some ideas. You will by the way also experience this political shift in the Netherlands pretty soon.
Haha touché :-)
And they proclaimed the Islamic Emirate of the Caucasus that was very similar to ISIS.
Also they didn't stop aggression after Russia lost the first Chechen war and they got their independence. They instead started attacking other non-Chechen territories in Russia that were peaceful until then.
The Russians were right to bomb the hell out of them. And we should do the same if these people don't stop attacking us.
The only way is to try to insulate oneself from these radicals by not letting them immigrate, or if it doesn't help pick an area controlled by the most vicious of these radicals (ISIS territory comes to mind) and give them a taste of what armageddon could look like so they'll learn an important lesson.
This has worked very well in the Chechen wars. The Russians tried negotiating, then they tried having a series of smaller military operations in order to take out their leaders. Then the Russians even conceded and gave them defacto independence, but It all didn't work. They instead went on to attack neighbouring Russian states and then even killed hundreds of Russian children in the Beslan terror attacks.
What did help though was Putins response completely levelling the Chechen capital Grozny. And I mean that literally because that's what they did. After that 99.99% of them became cooperative, in fact today most Chechens in Chechnya consider themselves fierce Russian patriots. I wonder why!
