Today we witnessed something in Congress that most of us would not have expected to see in our lifetimes: an Israeli Prime Minister came to Washington not just as the voice of Israel, but also of much of the Sunni Arab world. Bibi Netanyahu’s speech, excepting a few rhetorical references, was a crystallization of the policy that every Sunni, non-Iran-dominated capital holds today as well as Jerusalem.The Gulf Arab nations were not mentioned very often, but they loomed large in the background. (The Washington Post has the full transcript.) Bibi’s analysis of Iran’s recent progress in its hegemonic quest, his case that the oil crash gives the West fresh leverage when combined with sanctions, and his warning that this agreement would lead to a regional nuclear arms race—the King of Saudi Arabia would have said much the same. The oil crash, in fact, was Riyadh’s geopolitical masterstroke, aimed squarely at Tehran.This is the ironic accomplishment of the Obama Administration. Both Israel and the Sunni Arab states have become so alarmed by Iranian advances and the receding (as they see it) American security guarantees that they have made common cause. Both want Iran’s nuclear and conventional ambitions stopped (notice Bibi mentioned both today), and both want, as the late King of Saudi Arabia said, the head cut off the snake. Today, Bibi spoke not just for Israel, but for many of its Arab neighbors, too.
