Its too late to attack Russia. Ukrainian government has been criticized for its poor preparations for this invasion. When Russia was amassing thousands of troops in the Ukrainian borders the Ukrainian government was busy downplaying the eminent invasion because they were avoiding panic or anarchy. They would have began to evacuate civilians and recruited and train more fighters. Ukraine would have taken the fight to the borders. Rather they allowed Russia to have a free ride into the country.
Ukraine President was busy travelling to different European countries seeking for support but failed to prepare his people. Now instead of support he is receiving standing ovations.
Attacking Russia would make this war more bloodier and destructive. And Russia has many missile defense systems such as the S-550.
indeed if you do a genocide like ukraine you should have been prepared for an international retaliation,
the western elite still refuses to aknowledge ukraine's donbass genocide and tries to lie to its people about it and silence all those that mention it, like neonazis (holocaust) and stalinists (katin, holodomor)
we don't live in a moral regime we live between genocide deniers, arguing about who is more racist who is more nazi and who is less communist,
and secondly they all commited genocides and deny and justify them
welcome to late stage of human progress evolution.
where the good guy is being determined by who is more left and who is more gender and race left.
they ultimately need to appoint a genderless invisible ghost as their leader, only that would work without the ghost being difammed as a racist/nazi by any group
