Of course this was going to happen. I would think Latvia would be first but apparently not. Just like Islamic immigrants, Russians everywhere make it their personal business to colonize the countries in which they live and force themselves on the host population- just look at Israeli politics. What needs to happen is the integration of Russians into normal Latvian society, with no more self-ostracizing and seclusion, and financially-compesated repatriation for those who are loyal to Russia.
I agree. I would add that unlike the Russians, the Islamists have weaponized the family structure. They can’t win. They are too tribal and can’t build effective institutions, but they can do a great deal of harm.
