You could not break something which do not exist.It is kgbstan,not Russia.And it is arleady ruled by oligarchs - from KGB mafias.
And,if Ukraine was Manchukuo,then why they still fight?
Weapons alone do not fight,you need soldiers for that.
If they wanted divide kgbstan,they would do so arleady.Democrats always supported Moscow,and Biden wanted peace with Putin - if he only take part of Ukraine,not attacked entire territory.
And even now USA send enough weapons to stop kgbstan,but not to defeat them.
World woud be better if Moscov state ceased to exist,sadly democrats do not go for that.
