"The Middle East just does not have that much water to begin with, and it's a part of the world that will be experiencing less rainfall with climate change," said Famiglietti. "Those dry areas are getting dryer. The Middle East and the world's other arid regions need to manage available water resources as best they can."

“Morsy sends a clear message to the Gulf countries and especially the [United Arab Emirates] that he can easily create alternative strategic relationship,” Labbad says, adding that such “political vexing” is a response to the failure of the visit by Morsy adviser Essam al-Haddad to resolve the issue of 11 Egyptian detainees in the UAE. The latter are said to have strong connections to the Brotherhood’s international organization, in the midst of growing enmity between Egypt and the UAE.. Labbad argues that Morsy thus does not aim at real and deep rapprochement with Iran, but rather a cosmetic patch up to send signals to the Gulf. “The context here is very dangerous, because the revived relationship with Iran should be an addition to Egypt’s foreign policy, not a replacement of its relationship with the Gulf countries,” he adds. Momani doubts such an inclination by Morsy, as Egypt cannot afford the cost of such a policy. “This strategy can backfire and upset Gulf donors and benefactors. Iran can never supply the kinds of funds that are provided by the Gulf,” she says.

“I think neither Morsy nor Ahmadinejad enjoy the authority to have complete control or knowledge of their respective government’s grand strategies for Syria. What seems certain is that a realist agenda determines foreign policy on both sides. Both seek a Syrian government they can control or at least influence,”

Referring to illegal refugees, he says “everything is about money. The police look for their houses, steal savings and then deport them.”

He thinks that the slaughter in neighbouring Syria will lead to the overthrow of the Assad regime that back in the 1980s murdered his father, his friends and so many of his neighbours.

Muawiya is barely out of nappies and he would probably rather watch cartoons than Free Syrian Army propaganda. But his head is being filled daily with sectarian chauvinism and thoughts of war. As we interview his father, Muawiya starts firing an imaginary rifle made from a stick. He is very specific in his actions - it is an imaginary bolt-action sniper rifle

Out on the streets of Bab al-Tabbana we film other young boys playing war games. They take aim and shoot their toy rifles uphill towards Jabal Muhsin

Up on the Jabal, it is a mirror image. The kids point their plastic Kalashnikovs down the slope, as their fathers do in real life.

The young men who make up the militia on both sides look identical in their skinny jeans, knock-off Adidas weightlifter vests, baseball caps and Maori-style tattoos.
