My latest at the National Interest works through the deterrent capabilities of Israel’s sub force:
Do the Dolphins provide Israel with a credible second-strike deterrent capability? No, not by the standards of every other submarine deterrent force. The obstacles are too numerous to think of the Dolphins as representing the same sort of “dead hand” retaliatory capability that we associate with other sub forces. Israel has other, more capable and more survivable means of retaliating against Iran, or even launching a first strike. At this point, the Dolphins amount to “security theater,” an effort to convey the image of additional protection without actually providing much in the way of defense.
