I see you have very little knowledge of nuclear weapons effects. It's true Israel is a small country, but it's not that small. Esepcially considering that none of their enemies are likely to have thermonuclear weapons, limiting the potential yield of a single device to a few 10s of kilotons, at most, in anything delieverable by aircraft or missle. Even if they did, not even the big baby that the Soviets once exploded, which was something on the order of 50 megatons would "level" Israel. This site indicates that even a 50 MT weapon would only break windows at a distance of about 45 miles. It indicates that destructive radius of a bomb goes as the cube root of the yeild, and give window breaking distance for a 20MT bomb. Lots of small ones are better than one big one. Even so it would take 3 of those 50MT devices (the one was a one of a kind device, although it was air delievered), to even break windows over all of Israel.
