Earlier this month I called the Iran deal 'a recipe for war'. It turns out I may have been prophetic.
US Defense Secretary Ashton Carter is currently touring the region, trying to drum up support for the deal. He's making little (if any) headway. Earlier, Israel's Prime Minister had "not responded" to a proposal from President Obama to "upgrade the Israel Defense Forces’ offensive and defensive capabilities" in return for its support. I have little doubt that Israel's military planners have already moved Iran's nuclear facilities to the top of their targeting list.
Israel, Saudi Arabia and the Gulf states are also growing much closer in the light of the threat from Iran. A few months ago Israel reportedly offered its Iron Dome air defense system to Saudi Arabia to deal with missile threats from Yemen (although the Saudis turned it down). Now Saudi Arabia has echoed Israel's concerns in discussions with Ashton Carter, and made it clear that it will support - and join - military action against Iran if necessary. That may well include joint operations with Israel, a prospect unthinkable even a short while ago. I discussed this in 2013, and noted last year that the various and sundry threats in the Middle East were driving an Arab-Israeli rapprochement. Looks like that may happen a lot faster now.
As StrategyPage points out:
Saudi Arabia came out an publically agreed with Israel about what was wrong with the Iran treaty. The Israelis, Saudis and other Gulf Arabs agree that Iran is more likely to behave like North Korea or Saddam ruled Iraq rather than comply with the treaty and pull back on getting nukes. Inside Iran the new treaty is seen as a great victory and on the streets (and on the Internet) the average Iranian sees this as their well-deserved opportunity to get their nukes. Senior American military leaders are also not happy with the new treaty, some of them going so far to point out that Iran backed Islamic terrorists killed over 500 American troops in Iraq and Afghanistan since 2003. Israelis and Saudis can also point to citizens killed by Iranian terrorism. Gulf Arabs in particular are reminded regularly that Iranian propaganda still praises and encourages that sort of thing. Israel reminds everyone that Iran still holds national holidays where millions of Iranians are urged (sometimes coerced) to gather and chant their hatred for the United States and Israel and call for the destruction of these two enemy states. Many Gulf Arabs still call for the destruction of Israel, but their leaders now openly speak of Israel as a valued ally in the struggle against Iranian aggression.

StrategyPage noted in January:
While Arabs cannot speak out in support of Israel (or even cooperation with Israel against common enemies), such cooperation continues and since the 1980s has grown. Saudi Arabia has always been the major supporter of greater, and open, cooperation with Israel. It’s an open secret that this relationship exists, has existed for decades and continues to be useful for both Arabs and Israelis. This is especially true when it comes to common enemies like Islamic terrorists (especially ISIL) and Iran. Israel wants the Arab states to go public about these relationships but because of decades of anti-Israel propaganda most Arabs would violently protest against any Arab government that admitted the truth of the Arab-Israel relationship. Yet there is progress, however slow, towards openness about the Arab-Israeli cooperation.
Again, more at the link.
If the threat from Iran is great enough to overcome decades of Arab-Israeli enmity (at least at government level), then it's probably great enough to allow Israel to use air bases in Saudi Arabia and/or the Gulf States to hit Iran with air strikes. It may even be enough to allow an Israeli submarine or two, probably equipped with nuclear-tipped cruise missiles, to be stationed in the Persian Gulf and be supported from a local port (very discreetly, of course). This was mooted as far back as 2010, and may already have happened. From there, the submarine's 900-mile-range Popeye Turbo missiles can hit any target in Iran.
If I were the Iranian leadership, I'd be getting more than a little worried about all this.
