The Russians are having their ugly war brought home to them. It will be hard for the Russian people to pretend like nothing is going on as long as they are vulnerable. That is the threat of terrorism to large states and absolutist governments, and that is why our government in particular is trying to root out armed resistance by guerrilla and terrorist groups. How long could the US kill Colombians, Iraqis, Iranians, Afghans, Somalis if they had to worry about attacks on Americans? Americans must be kept shielded from the brutality waged by American foreign policy. The same goes for other large governments around the globe. The Chinese have their rebel Uighur. The Russians have their Chechens.
The Chechens have a violent history with Russia:
Conquered by czarist armies in 1859 after decades of war, but Chechens never accepted Russian rule. During World War II, dictator Josef Stalin ordered Chechens deported en masse to Kazakhstan. Many died; rest returned home in 1950s, after Stalin’s death.
Of course, it doesn’t help them that their ancestral homeland is rich with oil.
