Under a 10-year deal signed in 2007, Israel receives just over $3 billion a year in American aid, with stipulations that over 70 percent of that aid has to be spent buying US military hardware. An extension of that agreement, running to 2028, was principally agreed on by Barack Obama during a visit to Israel in 2013, but according to Haaretz, talks on its terms have been "preliminary and unofficial."

Among the purchases to be covered by the new deal are supplies of the V-22 Osprey tilt-rotor aircraft, which the US has refused to export to any other country, as well as up to 75 fifth-generation F-35 joint strike fighters, whenever they overcome their teething troubles. The US also provides technology, parts and rockets for Israel's missile defense systems such as the Iron Dome and Arrow 3.
