Robert Joseph: “I think it was, certainly, an intelligence failure of the first order.”

I believe that the Russian Government needs to be called to account in front of every international forum, because it has a bloated, obscenely large tactical nuclear stockpile, which makes no military sense.

Leaving any potential loophole would not be in our security interest or in the interest of improved United States-Russian relations.

We don't back up what we say. We don't impose consequences for red lines that are established and then crossed.

My skepticism is that we continue to apply cold-war approaches in our relationship with Russia.
