Two former policymakers discuss whether the longtime allies can move beyond tactical responses to their strategic challenges in the region.

In a rare public address in Washington, D.C., Israel's defense minister explained his government's strategy for dealing with challenges including the emergence of a direct Iranian front to the north and recurrent mass protests along the Gaza border to the south.
