There is NO positive outcome possible with military intervention against Russia and especially Putin.
All you hawks really think if the West gets its' proverbial dick out Putin will be so impressed he'll shuffle back to silly little country with his tail between his legs ? I think you lot never got passed playground posturing and apply that same pathetic logic to the grown up world because that's all you truly understand.
The first statement is undoubtedly true, and that is why there is no actual intervention against Russia, other than by the country they are trying to destroy.
As far as the second paragraph it just seems to be a continuation of the "West is wrong" rhetoric. No mention of Putin trying to impress the West by playground posturing and by getting his proverbial dick out first, which does tend to show he is impressed by shows of dickmanship.
There must be a continuation of talk and sanctions up until the point that Putin gets so emboldened by the military "success" of his war that he tries a similar thing with another one of his neighbours on some other self-defensive pretext, at which point appeasement may be seen not to be working and there will possibly need to be military action short of nuclear war. The clear danger in that is who knows if it will stop there.
Sanctions will work, up until a point, at which time China will bail Russia out by increasing support and trade to them to counteract the loss of trade with the West.
Let us get some things straight here... It is Russia who are the aggressors, using attacks on civilians, including hospitals, using siege tactics on cities, using cluster bombs and thermobaric bombs. But it seems sometimes as if, other than some weasel words about Putin as an individual being evil, it seems OK to blame the amorphous "west", despite no country of the west having attacked Russia, and there is no acceptance that something may be wrong with the way Russia goes about its activities or that their political systems have failed.
P.s. I happen to have lived through the Cold War and remember the real threat of nuclear war with the Cuban missile crisis and have no wish for me, my kids or my granddaughter to go through that again which is why talking must go on, with both sides actually listening and engaging.
