Russia Ukraine war, page-65143

There's a big difference between supplying arms and actively joining the war. If Russia has been retreating for the last 2 months fighting Ukrainian soldiers alone, joint Ukrainian-Polish forces would steamroll them out of Ukraine within the month. Poland is quadruple the population of Belarus, and comparable population to Ukraine. Belarus/Russia trying to cut off Poland's border would give them a clear justification to enter the fray.

I hope it happens, it would end the war.
