As the opening of the American embassy in Jerusalem plainly shows, the U.S. is going to be more closely linked to Israel including especially its security. Since the 1960s, Israel has concentrated its attention on ground and air forces. Because of new technology, Iran’s nuclear and ballistic missile programs, and Russia’s increased naval presence in the region to name a few, Israel—today and in the future—will have to look to the seas to defend itself.
Israel’s maritime strategy is not fully formed, nor is its outline detailed. This matters not only to Israel but to the U.S. which retains a vital interest in free navigation in the Mediterranean and the stability that powerful naval forces in the region help assure. The U.S. shares an interest with Israel in denying use of the seas to terrorists; and preventing the hegemonic power that Iran and Turkey seek. A robust Israeli navy and maritime strategy benefit the U.S. whose permanent presence in the Med is based in Spain and has been reduced to four ballistic missile defense destroyers where once two aircraft carrier groups and a large Marine amphibious ready group patrolled.
The Med has reverted to its historic template: the tensions and conflict that have characterized the area from the Trojan War to the Cold War are back. In the Eastern Mediterranean Russian naval presence is growing, the Lebanese state has become increasingly enthralled to the Iranian-backed Hezbollah terror organization while Iran regards Syria as another instrument to threaten the Jewish state. Turkey recently signed an agreement to build a naval base in the Iran-friendly Persian Gulf state of Qatar and continues to distance itself from NATO, and Chinese investments in the region are accelerating, as are the naval deployments of Iran.
