Not another anti-clarification! Adding ships if "the Israeli government acknowledges as an Israeli vessel"? What does this even mean? Already we've seen "Israeli-linked" but not flagged ships attacked, but no Israeli government statement calling them "Israeli." So are we then forecasting a change in the policy of Israel's government? Or would a remark by Netanyahu suffice?
I ran this question to my yachtsman/USN Commander husband. He agreed that I shouldn't go all the way to zero not because of a hypothesized change in government policy, but rather because there always are captains who steer their vessels into easily foreseeable disasters. It could even be an Israeli yachtsman with a ten-mile range transponder, enough money to afford to traverse the Suez Canal, and handguns for self-defense, and out for adventure. It may even be more likely than the Israeli government acknowledging a non-flagged vessel as an Israeli vessel.
