I really hope it stays like that. Lukaschenko is equally unpredictable. Because if Belarus joined, even though their army is bad, that would send a horrenuous signal. It would increase pressure on Ukraine even more regarding military and geopolitics. So far Russia basically fights on its own (not talking about supplies). But if Belarus joined, that would be yet another escalation towards whatever and Russia wouldn't be alone anymore.

I feel like the longer this war goes, the worse it becomes. Kind of like what happened with Hitler. Lukaschenko still could change his mind in I don't know, 6 months? One year? Two years? The war in Donbas has been going on for 9 years. The overall war could continue to go for another couple years, too. With all things that might happen
