Yep, it’s all about flexibility. GWB specifically allowed Russia flexibility to pull out by saying “IF it’s true.” That’s why all of the denials about occupying forward towns by Russian diplomats vs. Putin’s “logical end” comment. US is not standing down. Russia will not advance beyond probing attacks, which are all about staking out a negotiating position. They can pull back from the probes and allow ‘victory’ for both sides. Putin wants a foothold in the Caucasus. That’s his goal. Saakashvili will make that a major pain in the ass though, with constant agitating, hence their wanting him out. They think he’s given up his ability to peacefully cede SO and AbK. I don’t think US is going to let them have Saakashvili.
