Israel, and 8 other countries are sometimes called ‘nuclear club,’ since they possess nuclear weapons.
Among these 8 countries, 5 have signed the Non-Proliferation Treaty; US, Russia, Britain, France, and China.
India, Pakistan, and North Korea are three countries which have not signed the NPT, but carried out nuclear tests.
Israel is Middle East’s only nuclear weapons country, who has taken a policy of ambiguity in his nuclear weapons information.
According to US official statement, the US has currently 5200 nuclear warheads, with 2700 being operational.
The US warheads had explosive power of 1gigaton of TNT. This power is enough to move mountains, changing the river paths, weather change, and death of hundreds of millions or perhaps few billions of people on earth.

It is speculated that Pakistan has about 580 to 800 Kg. of enriched Uranium, sufficient for making 30 to 50 fusion bombs.
Israel is Middle East’s only nuclear weapons country. Despite international demands, Tel Aviv has not signed NPT, and in reaction to international pressure, on one hand, has announced NPT against its domestic security, and on the other, has taken a policy of ambiguity in his nuclear weapons information. By ambiguity, Tel Aviv has meant that it would not be the first country to "introduce" nuclear weapons to the Middle East, leaving ambiguity as to whether it means it will not create, will not disclose, will not make first use of the weapons or possibly some other interpretation of the phrase.
Estimations on Israel’s nuclear stockpile has provided a range of 75 to 400 heads, but most of estimations gives 200 as the number of Israel’s nuclear warheads.
