US President Biden spoke of false justification and a Russian "playbook" in his recent statement (cf. CBS News video Biden gives updates on Russia-Ukraine crisis following call with allies | full video after
05:07 (my transcription)):
...Russia's state media also continues to make phony allegations of a genocide taking place in the Donbas, and push fabricated claims, warning about Ukraine's attack on Russia without any evidence; that that's what Ukraine is thinking - attacking Russia.
All these are consistent with the playbook the Russians have used before. To set up a false justification to act against Ukraine. This is also in line with the pretext scenarios that the United States and our allies have been warning about for weeks. Throughout these tense moments the Ukrainian forces have shown great judgement, and I might add, restraint. They refuse to allow the Russian to bait them into war.
Question: What are the previous uses of false justifications for invasions used by Russia as used in it's so-called "playbook" from the perspective of the US?
I have heard "Russian playbook" repeated over and over in several different US news media outlooks, and a quick googling of the phrase returns "Putin's playbook" and "Kremlin playbook". Of course there will not likely be a literal book of plays printed out on paper, but with such widespread use of the term in English from so many sources, there must be something of substance here to which there is some level of agreement, some set of previous instances of false pretexts Russia has used for invasion. What are they?
Google Ngram for "Russian playbook" 1980 to 2019 shows low levels around the turn of the 21st century and a sustained rate of increase after about 2013:
