Reply #11: Actually Israel is generally thought to have a much larger nuclear force.

[Warren Stupidity]

Israel is the sixth nation in the world, and the first in the Middle East, to develop and acquire a nuclear weapons capability. Israel initiated its nuclear program in earnest in the mid-to-late 1950s, and by late 1966, it had completed the R&D phase of its first nuclear weapon device. Since 1970, Israel's status as a nuclear weapon state (NWS) has become an accepted international fact.

However, Israel's behavior as a NWS has been distinctly different from the behavior of the five official members of the nuclear club that have signed the Nuclear Non-Proliferation Treaty (NPT)—the United States, Russia, France, China, and the United Kingdom; and India and Pakistan, which have not signed the NPT. While these nations have publicly declared their nuclear status, Israel, to this day, has never confirmed or denied its nuclear status and remains outside the NPT. Since Prime Minister Levi Eshkol pledged in the mid-1960s that "Israel will not be the first nation to introduce nuclear weapons to the Middle East," all his successors have adhered to this opaque declared policy. This policy has become known as Israel's policy of "nuclear opacity" or ambiguity, perhaps the most distinguishing Israeli contribution to the nuclear age.

Israel is now an advanced NWS, in both quality and quantity of its arsenal. Estimates as to the size of Israel's nuclear arsenal vary significantly and range from fewer than 100 warheads to as many as 300. It is believed that Israel's current nuclear arsenal, along with its related delivery and command and control infrastructure, is comparable in quantity and quality to that of the United Kingdom and France (superior to that of India and Pakistan).

The "delivery and command and control infrastructure" is thought to include submarine based weapons that give Israel a survivable force.
