28. That's why Israel's nuclear position is to use them only when defeat is imminent

It's called the Samson Option, after the Biblical Samson destroying the pillars holding up a temple of his enemies, killing himself along with them inside.

Nevertheless, as early as 1976, the CIA believed that Israel possessed 10 to 20 nuclear weapons.[13] By 2002, it was estimated that the number had increased to between 75 and 200 thermonuclear weapons, each in the multiple-megaton range.[14] Kenneth S. Brower has estimated as many as 400 nuclear weapons.[15] These can be launched from land, sea and air.[16] This gives Israel a second strike option even if much of the country is destroyed.[17]

Israel has more than enough nukes, and the means to deliver them, to vaporize all the major cities of every nation in the region that may threaten them, including Pakistan. Hiroshima was 15 kilotons; a 1-megaton warhead is 66X more powerful. Their nukes aren't a deterrent to general warfare. Lobbing missiles and drones at each other, killing a few hundred civilians, etc. It's a deterrent to another mass invasion to wipe them out, like they fought off in the 40's, 60's and 70's.
