Putin didnt agree to anything. He is just toying with negotiators. And he is either laughing at Trump or expecting Trump to do nothing to Russia.
Trump has lots of leverage over Ukraine. Not so much over Russia.
I think Russia wants this to end as well.
It’s costing them dearly in treasure and people. Guns or butter.
I agree Russia has the upper hand and we don’t have the sort of leverage as with Ukraine, but Russia is also getting hurt in all of this and would like to see it end.
