An Egyptian proposal for a nuclear weapons free Middle East as part of the UN nuclear non-proliferation treaty (NPT) was blocked by the US, UK and Canada. The blockage was not unexpected since Israel which is not a signatory to the NPT had already indicated its opposition and on such matters Washington generally obliges Israel. The NPT 2015 conference ended without agreement and the US representative blamed the Egyptians – of course – for making a proposal that had no chance of success. The status quo continues and Israel can maintain all its nuclear warheads. The NPT conference will next be held in 2020.
It is not so surprising that all the western countries which created Israel and now protect its not-so-secret stock of nuclear warheads are the same powers who don’t want any possibility of Iran developing its own nuclear weapons. I can quite accept that Israel will want to protect its own interests. The position of the US and its allies is entirely expected but is also just plain hypocritical. But the myth of Israel not having any nuclear warheads can be put to rest for ever. If they didn’t have any there would be no point in blocking the Egyptian proposal.
Jerusalem Post: After four weeks of negotiations on ways to improve compliance with the pact, there was no consensus among its 191 signatories. US Under Secretary of State Rose Gottemoeller announced there was “no agreement” and accused some countries of undermining the negotiations. Gottemoeller did not name any countries but diplomats said she was referring to Egypt. …….
Last month, Egypt, backed by other Arab and non-aligned states, proposed that UN Secretary-General Ban Ki-moon convene a regional conference on banning weapons of mass destruction (WMD) as called for at the 2010 NPT review with or without Israel’s participation, without agreement on an agenda and with no discussion of regional security issues.
Those conditions are unacceptable to Israel and Washington.
Decisions at NPT review conferences, which are held every five years, are made by consensus. …….
Egypt’s proposals, Western diplomats say, were intended to focus attention on Israel. Washington and Israel say Iran’s nuclear program is the real regional threat. Iran says its program is peaceful. It is negotiating with world powers to curb it in exchange for lifting sanctions. Israel has said it would consider joining the NPT only once at peace with its Arab neighbors and Iran.
There were disagreements on other aspects of the NPT but delegates said the Middle East issue was the most divisive.
And in the meantime ISIS has announced that it is trying to get hold of one of the Pakistani warheads to be able to do something spectacular.
The Israeli nuclear stockpile of nuclear warheads probably lies between 100 and 400.

Estimates for Israel’s nuclear weapons stockpile range from 70 to 400 warheads. The actual number is probably closer to the lower estimate. Additional weapons could probably be built from inventories of fissile materials.
