That was because the Ukrainians had violated the agreed boundaries and were attacking the Russians in the Donbas through their mercenaries (the neo-Nazi Azov brigades) and by missile attacks from the Ukraine.
Some 13,000 Russians in the Donbas were killed over a five year period. Ethnic Russians in the Ukraine (where there had been a population for decades) were forbidden to speak Russian, prohibited employment, and subject to attacks by the Ukrainian thug services.
The former Ukrainian President was trying to abide by the agreements and also root out the corruption that was fueling it. Biden got rid of him through Hunter and his activities, and Zelensky…a comedian previously famous for playing the piano with his penis on TV and dancing in gay disco reviews while he was played the president in a Ukrainian version of West Wing…then became the hero and savior of the Ukraine. And ramped up the attacks on the border areas and violated the treaties.
I’m not even sure all of NATO wanted to be part of it, but the threat of withdrawing money (as Hunter had done with the prosecutor) does wonders for ensuring cooperation.
You certainly have all of Moscow’s lies down pat. In reality land Donbas Russian speakers like my wife’s family spoke Russian all the time, are patriotic Ukrainians, and greatly resent the Russian and Mohammedan thug occupiers.
Moscow started the fake separatist movement through agents, bribes, threats, disappearances, other mafia tactics, and finally troops.
“violated the agreed boundaries”
There were no “agreed boundaries”. The agreement was null and void when Russia refused to uphold its end of the bargain and disarm the revolutionaries that it had armed and funded in Ukraine.
