The Jackson-Vanik amendment was only repealed in 2012, at the same point when the Magnitsky act was signed. I don't think Putin & co see a lifting of sanctions as a possibility, given past experience.
Ok, that doesn't change the fact that all that is happening is that they are losing more and more lives, military power, and are suffering significant economic damage.
Thats the point. They are taking nothing but losses. All for some land that is now worthless after the war.
They obviously see things differently. You cannot claim that the particular sanctions regime in place pushes Putin & co towards your desired course of action without understanding their motivations.
Oh they are absolutely have motivations against their own people dieing in the hundreds of thousands and they have motivations against them losing significant military assets and having massive amounts of economic damages.
Those are normal motivations they every county has.
That's why the best way to get them to change behavior is to "motivate" them with those consequences.
Current analysis is that Russia has maybe another year and a half left in their war before it ends due to these "motivational factors".
