Do you reference for that claim?
We're the ones being flooded with immigrants sucking up tax dollars from our cities and states. Who knows how many Muslim terrorists are flowing over our border along with the Chinese nationalists, drug and sex traffickers, gang members and violet criminals.
We and Europe are the ones with pro-Hamas protesters disrupting our countries, not Russia.
Your post is actually classic case of projection. Everything you're claiming is going to go wrong in Russia is going wrong here. Yet, your focus on Russia. Go figure.
The problem of illegal immigration to Russia has been covered frequently in the Russia news media and in official statements. You are, I am confident, capable of finding examples of that through internet searches.
