It's naive in the extreme to think that Russia was an innocent and neutral bystander in the Minsk agreements, that is Minsk, the capital of Belarus, and you insult members' intelligence by constantly asserting that this is so.
It is dishonest of you to put words into my mouth. Russia helped draft and then took the agreements to the UNSC. I have stated this quite clearly. The parties to the agreement are;
1) Ukraine government
2) Leaders of the breakaway republics
There are no 3 or 4. The only parties that could break the agreement are 1 or 2. There are no other options. 1(Ukraine gov) admit entering agreement in bad faith and breaking it from the start.
The Guarantors for Ukraine (France & Germany) have also admitted that they only acted as guarantors as a means to buy time for future aggression. Do you believe that Ukraine, Germany, France, NATO are "innocent and neutral bystanders"?
What do you consider the Ukraine/NATO role in this? Do you honestly believe that "Russia invaded" with no provocations?
Why and how do you think Minsk was agreed in the first place? What do you think led to it becoming a Security Council resolution? When you delve and understand the answers to those questions then you would also understand who broke them. The answers to those questions peel back the RealPolitik of everyone's role in this.
Start at Debaltseve and things become clearer.
I have stated previously that Russia were under no illusions that Minsk 2 would be successful. They knew it would be ignored and broken immediately. You perhaps should wonder how Russia got Ukraine and their NATO sponsors to agree to the Russian led and drafted agreement and to then allow it to pass without veto at the UNSC.
Russia were demonstrating to the ROW that the West were and are "agreement incapable". The "forms must be obeyed". I don't claim that Russia are "an innocent and neutral bystander in the Minsk agreements", whatever that means. I understand Russia's role as well as NATO's. You have a wildly distorted view of Russia's role only.
Minsk 2 was everything Russia wanted. They drafted it and held a metaphorical gun to NATO's head to ensure NATO/Ukraine agreement. Why would Russia breach an agreement drafted to suit exactly what they wanted?
What happened to make Ukraine/NATO agree to this?
