I don't disagree with the Russian conclusion on this. No deal! But for opposite reasons.
In fact, nuclear reductions are a side-show. Both sides will retain enough nukes to destroy the planet whatever happens. The thing that mattered were the sanctions, which were imposed on the murderous Russian leader by Obama. They clearly hurt Russia and explain Putin's hatred of the Democrats, and Obama in particular.
So Trump was offering the Russians a nominal change in military capabilities in exchange for the end of costly sanctions. It was a lousy deal for the Western world. Obama's sanctions are clearly working. And Putin's effort to hit back via cyber-activities should lead to more of them.
