With the trashing of Minsk 2 by NATO proxy Ukraine, independently observed and recorded shelling of civilian areas, Ukrainian troops amassing in preparation to invade and "cleanse" the local population- Russia had a stark choice.
On 21/02/23 Putin recognised the sovereignty and independence of the two breakaway republics after a vote in the Russian Duma requesting this. Putin recognised the self declared independence of the two republics.
With all diplomatic solutions exhausted and Ukrainian armed forces killing their own "wrong" civilians- Russia, acting under Article 51 of the UN charter and the Responsibility to Protect doctrine, pre-empted the Ukrainian aggression.
From playing a role in negotiating the agreements, taking those same agreements to the Security Council, ensuring independent observation, attempting to force Kiev and their sponsors to abide by and fulfil Minsk 2 agreement- Russia did everything possible, through the correct legal and diplomatic channels to prevent hostilities.
Only then did they invoke Article 51 and R2P.
The ROW understands this. Only information starved Westerners are ignorant of these facts. Everyone outside of the West understands that NATO provoked Russia via their proxy Ukraine.
The ROW also remembers NATO using the R2P doctrine under Article 51 of the UN Charter. NATO didn't bother with any of the legalities that Russia did, as shown above, over a number of years.
No Security Council resolutions, no independent observations. A few media reports was basically the grounds for NATO acting under R2P.
Despite your training telling you otherwise, a more balanced and objective view understands the difference between the legality of actions taken by NATO and Russia.
Russia have legal justification for all Russian troops deployed outside Russia.
What is the legal justification for NATO troops in Syria? Ukraine? Are they co-belligerents or not?
The Rest of The World is well aware of who the bullies are. It isn't Russia that they want bringing down. Russia don't sanction, bully and threaten them.
