Joe gives an interview at 1:30 on Russia Today on New START.  He stresses the importance of the treaty and its impact on U.S.-Russia relations.  He says:

It is absolutely imperative, as out top military officials have testified, that the countries with the two largest nuclear arsenals in the world have predictability and transparency over their arsenals...This will make real reeducations in long range weapons. Most importantly, it will reestablish a process of inspections so Russians will be able to see what we’re doing, the US will be able to see what the Russians are doing and finally, it opens the way for greater global action on the other security threats, like North Korea, Iran and nuclear terrorism. Security wise: a very important treaty.
