the bit about the US gambit is BS...utter nonsense ....and it is NOT true .....only yur propaganda ....there was no US plotted coup in Ukraine .....the peole chose then , and they have chosen since ......there is NO justification for putin top invade to conquer .
the bit about the danger of using tactical nukes is actualy real I say , danger , because it wouldn't have to escalate to a full on nuclear conflict .....I'm sure the west would not respind initialy with any sort of nuke ....but could happen down the road of russia persisted .
But putin can not be allowed to be successful in nuclear blackmail .....or it will be repeated .That problem of nuclear b;lackmail just happens again and it looks just like the appeasement of Hitler .
Nor can putin be allowed to to succeed in conquering Ukraine .....as that also would be repeated elsewhere ....putin made this plain in his Peter the great speech .
These are the things you try not to look at ....one way or aniother this war is a precedent and allowing putin to have any sort of win is just kicking the can do the road and inviting repetition at a time of putins choosing ....in Ukraine and elsewhere .
