This has already happened. Just as in the US, all of the far-right "movements" in the EU are Russian fronts.

The two biggest targets are the UK and France, because both have an independent nuclear deterrent. If those are captured by puppets, expect nuclear explosions over European capitals.

This is not hyperbole. Russian government insiders have made it absolutely, unambiguously clear that Europe must be "crushed."

As a direct quote.

The real tragedy is oligarch complicity. Oligarchs and aristocrats in the US, UK, and EU have decided they have more in common with their Russian counterparts than with the native populations of their respective countries.
