What are your thoughts on the Donbass war (2014-2022)? Were the separatists russian puppets or the expression of (parts) of the local population? And what’s your views on the non-implementation of the Minsk agreement ?
The separatists were Russian proxies, full stop. The tapes from Glazyev clearly prove that, and opinion polls in those provinces show that even in Crimea, native Russian weren't enthusiastic on the idea of being annexed or controlled by Russia. Hence, the rebellion was largely manufactured out of whole cloth, and when paid demonstrations failed, Russia responded with importing irregulars to pose as native separatists. Here is an exhaustively well-researched report on exactly what went down with that, and when even irregulars failed, Russia had no choice but to launch its own invasion with its regular forces in 2014.
The idea of a "Donbas genocide" or "Donbas shelling" is a myth. It's a blatantly revisionist take that argues that while the Russian-led separatist forces were allowed to attack and shell the Ukrainians (more casualties were caused by Russians and Russian-led separatists), Ukraine was not allowed to defend itself or conduct counter-insurgency operations against an insurgency in its own territory.
The idea that "the Minsk agreements secured peace, but Ukraine refused to implement it" is likewise false. For one, Russia also habitually failed to implement its own provisions, conducting its own rigged elections in Donetsk and Luhansk contrary to the stated provisions of Minsk. For two, all foreign groups, i.e. Russia's imported forces, were to be removed, and they weren't. For three, Ukraine was supposed to have full sovereignty over its border, which Russia routinely transgressed to resupply its forces. It also blatantly broke the ceasefire to seize more territory. Russia pretended that it held no control over the separatist forces, but that was a transparent lie - repeated investigations and even testimony from the separatists themselves said that they took orders from Moscow.
Pretty much all the arguments are largely post-facto justifications to support Russian deniable asset wars. For all the claims of the Euromaidan being a "CIA-sponsored color revolution" (pro-tip: if someone uses those words unironically, you don't have to take anything they say seriously, they're just an unthinking consumer of Russian disinformation), the "Donbas separatists" were actually far closer to what that operation would be like in reality - imported agitators to create a false appearance of a separatist movement with military support to overthrow an existing government.
