"On 17 February, President Joe Biden announced that Russia would attack Ukraine in the next few days. How did he know this? It is a mystery. But since the 16th, the artillery shelling of the population of Donbass had increased dramatically, as the daily reports of the OSCE observers show. Naturally, neither the media, nor the European Union, nor NATO, nor any Western government reacted or intervened. It would be said later that this was Russian disinformation. In fact, it seems that the European Union and some countries have deliberately kept silent about the massacre of the Donbass population, knowing that this would provoke a Russian intervention.
At the same time, there were reports of sabotage in the Donbass. On 18 January, Donbass fighters intercepted saboteurs, who spoke Polish and were equipped with Western equipment and who were seeking to create chemical incidents in Gorlivka. They could have been CIA mercenaries, led or “advised” by Americans and composed of Ukrainian or European fighters, to carry out sabotage actions in the Donbass Republics.
In fact, as early as February 16, Joe Biden knew that the Ukrainians had begun intense shelling the civilian population of Donbass, forcing Vladimir Putin to make a difficult choice: to help Donbass militarily and create an international problem, or to stand by and watch the Russian-speaking people of Donbass being crushed.
If he decided to intervene, Putin could invoke the international obligation of “Responsibility To Protect” (R2P). But he knew that whatever its nature or scale, the intervention would trigger a storm of sanctions. Therefore, whether Russian intervention were limited to the Donbass or went further to put pressure on the West over the status of the Ukraine, the price to pay would be the same. This is what he explained in his speech on February 21. On that day, he agreed to the request of the Duma and recognized the independence of the two Donbass Republics and, at the same time, he signed friendship and assistance treaties with them.
The Ukrainian artillery bombardment of the Donbass population continued, and, on 23 February, the two Republics asked for military assistance from Russia. On 24 February, Vladimir Putin invoked Article 51 of the United Nations Charter, which provides for mutual military assistance in the framework of a defensive alliance."
