Leaving the Iran deal would play right into Putin's hands, says a former US ambassador to Russia

Supporters of the Iran deal have no shortage of reasons for president Donald Trump to stick with it: The deal appears to be succeeding in its aim of forcing Iran to cut its nuclear stockpile. All of the closest US allies back the deal (except Israel and Saudi Arabia). Backtracking on promises would damage the USs chance of a deal with North Korea.
Michael McFaul, former US ambassador to Russia and author of the new memoir From Cold War to Hot Peace, has one more reason to keep the deal: Abandoning it would play right into Russian president Vladimir Putins narrative that the US is untrustworthy.
McFaul worked on the Iran deal under Barack Obama. In a phone interview with Quartz, he recalled the lengthy talks held between the Obama administration and the P5+1 (the five permanent UN security council members plus Germany, which allied to negotiate the deal with Iran) to create the deal. Based on the Trump administrations current lack of diplomatic enthusiasm for renegotiation, McFaul predicts the US will walk away from its historic agreement.
