US - Russian ties were damaged with Russia’s invasion of Ukraine. This is just the playing out of that initial act.
The damage started way before that, I'm afraid. Hanging rainbow flags outside the US Embassy in Moscow, for the entire month of June each year, was an "in your face" to the Russians.
What's happening between Russia and NATO on Ukrainian soil is essentially the military "playing out" of a culture war, rather than a simple "land grab" as you and several others like to portray it.
To recover the total value of all their losses.....
Adept, as always, at confounding the issue and moving the goalposts.
Medvedev is not talking about recovering the "total value of all their losses". He's talking specifically about recovering the value of Russian sovereign state assets confiscated by G7 nations, currently valued at around $350 billion.
