Dick Lugar: “I have come to this hearing from an equally vigorous debate, over breakfast.”

In the likely event the INF Treaty collapses in August, the only remaining bilateral U.S.-Russia arms control agreement would be New START, which expires in 2021 but can be extended by up to five years through agreement by both parties.

That is a very dangerous attitude to take.

It seems to me to be really a safety net there.

There is precedent for using patient diplomacy to resolve treaty violations.
