US and Iran likely to team up to vaporize pro-Saudi wahhabi terrorist army?

Imagine that!  Iran becomes an ally of the USA?  

Robin Wright writing at TheNewYorker:
....On Monday, Iran and the United States,  along with envoys from Britain, China, France, Germany, and Russia, will meet again in Vienna to work on specific terms for a nuclear agreement. The talks resume just as Washington and Tehran suddenly find that they have common cause in preventing Iraq’s abrupt disintegration. For both, their longtime strategies toward Iraq appear to be failing, as a few thousand thugs in the Islamic State of Iraq and Syria (ISIS) burn their way across the country.

Washington and Tehran have started using the same language. President Obama, in his remarks on the South Lawn of the White House on Friday, said, “Nobody has an interest in seeing terrorists gain a foothold inside of Iraq, and nobody is going to benefit from seeing Iraq descend into chaos.” An hour later, Iran’s Foreign Minister, Javad Zarif, told me, by telephone, from Tehran, “It is in the interest of everybody to stabilize the government of Iraq. If the U.S. has come to realize that these groups pose a threat to the security of the region, and if the U.S. truly wants to fight terrorism and extremism, then it’s a common global cause.”

Obama said that Washington is “going to pursue diplomacy” across the region. Zarif told me that he’d been working the phones with Iraq’s neighbors for the past two days. Obama warned of the dangers of the Sunni extremists trying to “overrun sacred Shia sites.” Iran is the world’s largest Shiite country, and its interests in Iraq are focussed on protecting the Shiite plurality that was long dominated by a Sunni minority.

Twitter pundits are already speculating about the potential for de facto coöperation between the countries. Among the scenarios: U.S. drones striking ISIS targets and, in effect, providing air cover for Iranian Revolutionary Guards dispatched to help hold back the ISIS jihadis, who have been pushing toward Baghdad. In our conversation, Zarif denied reports that Tehran has already dispatched battalions of Revolutionary Guards to aid and protect Prime Minister Nuri al-Maliki’s government, but its élite Quds Force has long had a presence—in various forms—inside Iraq....
