Well, my English doesn't seem good to comprehend this post entirely. So, I maybe just expand my thought about the matter.
The main problem of the dimwits who support prolonging of this war is two mutually exclusive conceptions - 'Russia is too weak that it can't even deal with Ukraine' and 'Russia, after taking over Ukraine, will go on and attack some NATO country'. Naturally, such concepts can't exist in reality simultaneously, but exist in such people's heads. They can't reject either one due to the lack of integrity or basic common sens and just repeat one or the other depending on which one suits them at the moment.
Out of those two misleading ideas stems the notion 'Russia should be pushed out of Ukraine, otherwise it will launch, after a while, another invasion'. When you try from the opposite side and ask 'If pushed out, why can't it launch the same', usually only silence is presented as an answer.
So, to really stop this war, a sane approach should prevail that will abolish this unnatural 'duopoly in one' and finally come to an answer whether Russia is 'too weak' or 'strong enough'.
