I didn’t say that Russia has any just reasons to break any international agreements, because it doesn’t.
However, we’re talking about Minsk II, that looked to me like a good deal for all parties involved, and I think it had the potential to bring peace to these lands first time in 20 years.
In what world is Minsk II a good deal for all parties?. It literally gave Ukraine nothing aside from "we stop killing your soldiers". It did exactly what Russia seeks to do, freeze conflicts so they can start them again.
the Budapest Memorandum was broken In 2014 when Russia first invaded.
You still haven't given me a reason why Russia gets to unilaterally break there agreements.
