Lol, that’s not a way to talk to someone. You don’t know what the next person capable of. We Paki have the problem of polarised politics.
Social science is not a math it has many aspects and I respect your opinion.
And as you said it’s difficult to research, yeah of course it is, below I’ll add some references for books of some political scientists. If you do give them time.
What I see are four scenarios:
Scenario 1: Foreign Imposed Regime Change
Putin seeks to establish a pro-Russian regime in Kiev. Ukraine remains independent, but is "supported", indefinitely, by Russian forces.
Book: Topling foreign governments; The Logics of regime change
Scenario 2: State Death
Putin seeks to annex all of Ukraine into Russia.
State Death: The Politics and Geography of Conquest, Occupation, and Annexation
Scenario 3: Imperial Overreach
Putin's ethno-nationalism, combined with security paranoia, leads him to seek recreation of the entire Russia Empire/USSR. All of the "near abroad" is the next target.
Scenario 4: Major Power War
Putin specifically shifts his focus to the Baltic States. Despite being NATO members, Putin, in his mind, senses an opportunity to strike and correct the mistake of letting them "join the West"

I even have analysis on Which scenario is most likely But it’s not a platform to debate. Leave it.
