You make good points. However, although Russia has a large muslim population, approx. 11.7% currently, Russia ‘manages’ them more tightly than the U.S. and the West in general. An example is that the 2 million muslim residents & up to 2 million migrant workers in Moscow only have access to 4 mosques, with each mosque to accommodate 10,000 muslims only. Am on mobile & can’t send a direct link. But if you read wiki’s ‘Islam in Russia’ it’ll give you a pretty accurate pic of how the Russians keep a tight lid on their muslim population & neighbours. Tatars & Chechens are their biggest threats at present. Additionally, no doubt the Russians & the Chinese would have no qualms in using direct & brutal force should it become necessary.
And you think “ keeping a tight lid” will make it LESS likely they have a violent problem? As they grow in relative strength in the population?
Don’t think so.
