You seem to have problems coping with reality.
I merely pointed that economic sanctions as a tool for regime change generally don't work.
The proof of that is in the fact that the Americans are now offering to lift economic sanctions on one dictator in order to impose them on another dictator.

As far as i know they are eager to get Iranian oil flowing again as well.
...and Maduro is still running the show in Venezuela.
Now the Americans have decided go one better and sanction the Russians even though experience shows that it may not get rid of Putin.
America sent a delegation to Venezuela at the weekend to begin preliminary discussions with Maduro for their oil. And try to pull the regime away from Moscow. Good luck with that.
I wish they'd stop trying to find a way to drag Europe into the conflict. I watched an interview with Vindman, Trumps NSC advisor, last night and he persisted in the attempt to send aircraft to Poland, have them enforce a no-fly zone over Russia and insist Poland can do this as a sovereign nation; conveniently forgetting they're also a member of the EU.
Russia would almost certainly sanction gas supplies to Europe and say they were right all along about NATO aggression.
Another American (military) analyst gave an interesting take on the Russian convoy, north of Ukraine, in an interview with the New Yorker, where he thought they'd simply surround Kiev and bite a chunk off Southern Ukraine; then sue for an armistice on their terms.
The latest strategic maps certainly seem to indicate such a move is possible, although it's very difficult to predict such an outcome at this stage.
On a personal angle, it intrigued me as i used this strategy to great effect when playing Civilisation V - 'The Hammer and the Anvil': where you use one wing of your armies to hold the enemy in a defensive battle of attrition, then swing round with armoured forces to crush him between your army groups.
It sounds easy, sitting here, drinking coffee, munching toast, listening to the radio...but in the world of Realpolitick there's no simple solution to this violence.
