The State Department has issued travel warnings for Israel (Level 3, "Reconsider Travel") and Gaza (Level 4, "Do Not Travel"). Not insane, though a bit generous, I would think: other than high-level diplomats, military personnel, journalists, and people with dire need, who in his mind would travel to an active war zone, which clearly includes all of Israel, not just Gaza.
What makes it very odd, in my mind, is knowing the greater picture: not long ago, many of the world's countries, including safe, first-world Switzerland, were given the dreaded Level 4 Do Not Travel status. Because you might catch Covid there. Never mind that you could just as easily catch Covid by staying home. And that for someone who is healthy enough to travel, the consequences of catching Covid are a whole lot less significant that the consequences of being blown up by a missile or a bomb, or raped/killed/kidnapped by a terrorist.
As I've said before, the Level 4 warning is so broad as to be almost meaningless. It needs to be re-evaluated.
