For such a low-key guy, Cool Hand Barry is forging quite a legacy at the White House.

President Obama's nuclear deal with Iraq, an agreement forged in conjunction with five world powers, stands in tandem with the Affordable Care Act as the Administration's landmark achievements.

Obamacare ranks with FDR's Social Security Act and LBJ's Civil Rights Act as the three most important domestic laws passed by Congress in the last 100 years.

Both Obama wins faced near unanimous opposition from Republicans, a party that tried to "de-legitimize" the President before he even took the oath of office.

The Iranian pact offers the potential to foster political change in Iran from the hard-core mullahs to more western-oriented younger leaders. That dramatic shift would re-order the Middle East.

Critics rap the deal's 15-year term, saying the President should have fought for a better agreement.

They deny reality.

Iran would never agree to re-negotiate the agreement.

The New York Times reported today representatives from Russia, Britain, Germany, France and China—the US partners--told Congress the same.

They said the agreement is the only one possible and warned Congress their own sanctions would be dropped if it voted down the agreement. In that scenario, the US would have lost diplomatic credibility and become isolated from the global powers.

The Iranian nuclear deal is one of hope. As in life, the agreement carries no guarantees.

Supporters and critics of the deal agree the military option remains available if Iran breaks the agreement.

In pushing for the deal, the President opted for a brighter future for all. He earned a great victory.

Obama now pursues a legacy trifecta, achieving a breakthrough on warming at the global climate change conference in Paris this December.

A global warming pact would be a fitting way to cap a successful presidency.
