As for deporting all Russians, well, they all pose a risk. How many of them actively support Putin's regime? Do you know?

They have to be deported now or will have to be interned later.

All supporters of Putin in the West must be arrested and deported NOW. You can vet and deal with the rest later.

Russian imperialism kills people. If you underestimate it, you are in danger.

The West should stop diplomatic relations with Putin's Russia.

PS. Support of Putinism should be illegal in civilized countries.
