Nuclear fall out respects no borders. The massive levels of fall out from a nuclear war would poison every one on the planet. Every country would be the loser not just Russia. Do you not get it: a nuclear war would be the end of humanity?
It still is political theatre used by Biden to divert attention from his lamentable poll ratings.
The Minsk peace accords of 2014/15 placed an onus on Ukraine to carry out a series of political/military measures, which it has steadfastly refused to implement. Instead it has waged war on Russian speakers in the Donbass.
Ukraine is no democracy. Opposition politicians are in jail, numerous political parties are banned, journalists/newspapers closed down, never mind the numerous atrocities committed by neo-Nazi military units such as the Azhov battalion and the Odessa massacre of May 2014. In Ukraine the state allows and encourages the open celebration of war criminals from WW2 such as Stepan Bandera. The US/NATO have armed the Kiev junta to the teeth and encourage it to keep shelling civilians settlements in Donetsk and Lugansk. Don't take my word for it. You should read the daily reports produced by the OSCE which clearly reveal that the majority of shelling is coming from the Ukrainian army.
