Leslie and callers discuss today's announcement that, after no diplomatic relations between the U.S. and Iran since 1979, a historic preliminary nuclear agreement has been reached between the nations and five other world powers.

Some of the items discussed are:
-The specifics of the deal
-How big of a deal this is in historical terms
-Whether Congressional Republicans and/or Israeli Prime Minister Netanyahu will try to sabotage the deal
-Whether this agreement will become one of the greatest accomplishments of Barack Obama's presidency if it prevents Iran from building a nuclear bomb
