From invasion or forced regime change? Yes (But I don't think the nukes actually helped in that regard).

Pretty safe if you ask me, judging from their…location and historical context.

Historically, Israelis have been much safer than most of their neighbors Oct. 7th notwithstanding.

The last time Israel faced an existential threat from its neighbors was 1973. The timeline isn’t entirely clear, but that’s right around the time when they started to have operational nuclear weapons. Many factors contributed to their relative safety since then, but the timing certainly works out for nuclear weapons helping to make that true.

Well, proximity is a factor...
