or maybe he and europe know belarus really don't want to join the war , unlike go to war along side US as their minions where US air power own the sky : there are no need to worry about enemy artillery , SAM , guild rocket blow up your ground force convoy
it basically a fun hunting trip with minimum casualties
RU air power just suck can't own ukraine sky can't destroy ukraine hidden sam , artillery , himmars 24/7 allow friendly armor force , CAS freely roam around roftstomp ukraine ground force
joining war along side russian right now is basically suicide and stupid specially for belarus : they have very limited hardware and man power can't afford to let them burn by ten thousand and more like russia
lukashenko grip on power also not really strong as putin : the last thing he want to see is belarus people angry seeing thousand of belarus tank/APC , hundred of belarus aircraft (not sure they have that number) , and ....whole lot of infantry burn and die in ukraine .
he show no interest joining russia in 2022 where people who like russia side still watch this video with big smile on their face , putin with all the power can't even sway him
lukashenko sure as hell not going to join the war today unless ukraine stupid enough attack belarus and kill whole lot of civilian (which zenlensky will never do)
unless putin and russian FSB can do some....good old ...Operation northwoods inside belarus
