Senator McCain is right when he says Russia's economy is a gas station and Russia is a gas station posing as a country.

If we don't have European allies, going forward, and we have a large trade war with Europe, I worry that not only our policy toward Iran but our policy in many areas of the world will be harmed.

I do think, as you said, that decertifying this deal or at least in some way pulling away from this deal is going to make it harder to negotiate with the North Koreans.
