Just to be clear: you started the war in 2014, Russia will finish it. 
Russia's Mr. Sergey Lavrov of @mfa_russia  will run you through the definition of what the "just peace" is. 
While you and your European cheerleaders may think that stealing Russia's assets is free money, let me assure you that those stolen Russia's assets will be accounted for and recovered plus interest when the "just peace" is defined by primarily Russia and also the USA (your mate @10DowningStreet is also irrelevant here). 
A bit of advise here pal: 
1. if you don't ask (politely) Russia to seat down to a peace agreement, the next time you will be meeting the Russian delegation is to sign the Unconditional Capitulation, just like your heroes Nazis had to do. And possibly without your presence, just like it was with Hitler. Amazing how history has the tendency to repeat itself, mainly because morons don't learn from it. 
2. Ask your European cheerleaders to help you secure "just peace", rather than having them egging you on, to continue the senseless killing of your banderite comrades. See what sort of reaction you get, you may be surprised. 
I know that you are a mule for your oligarchs and your job is to do money runs around the world, but this has really short legs mate. 
3. Take your Stefan Bandera's 5th Column the fuck out of Poland or Poles will do it for you and it won't be pretty. Tusk or no Tusk @PremierRP . 
4. Stop taking that shit.
