My take is that the European political elite are desperate to do any and everything to stave off the end of this war because once the guns stop and the smoke settles then there is going to be a reckoning. Of any and everything.
So just for starters, Johnson's role in scuppering an earlier peace-deal, MI6 and its role in formulating much of the s***, Norstar 2, the despicable lies told in the so called 'Free' Western press and so on and on. And that is just the UK. France and Germany have their own versions as well.
There are multiple tons of s*** about to fall when this war stops. And we have a collective set of politicians in the West who know vast amounts of it will fall on them.
If this peace deal does go through, then it will be the biggest foreign policy humiliation for the UK since Suez. And will reverberate for decades. Russia has gone from strength to strength and once it emerges victorious, then will cast a shadow over the EU for a long long time to come. Not in terms of any kind of direct military threat but rather because of the sheer amount of political payback that will land in London. Paris and Berlin.
