Pakistan is not a member of the?Nuclear Non-Proliferation Treaty?either. Pakistan covertly developed nuclear weapons over many decades, beginning in the late 1970s. Pakistan first delved into nuclear power after the establishment of its first nuclear power plant near?Karachi?with equipment and materials supplied mainly by western nations in the early 1970s. Pakistani Prime Minister?Zulfiqar Ali Bhutto promised in 1965 that if India built nuclear weapons Pakistan would too, "even if we have to eat grass." The United States continued to certify that Pakistan did not possess nuclear weapons until 1990, when sanctions were imposed under the?Pressler Amendment, requiring a cutoff of U.S. economic and military assistance to Pakistan.?In 1998, Pakistan conducted its first six nuclear tests at the Chagai Hills, in response to the five tests conducted by India a few weeks before. Over the years, Pakistan has developed into a crucial nuclear power. It's also alleged that Pakistan is still drastically increasing its nuclear stockpile.

North Korea was a member of the?Nuclear Non-Proliferation Treaty, but announced a withdrawal on January 10, 2003 after the United States accused it of having a secret uranium enrichment program and cut off energy assistance under the 1994?Agreed Framework. In February 2005 they claimed to possess functional nuclear weapons, though their lack of a test at the time led many experts to doubt the claim. However, in October 2006, North Korea stated that due to growing intimidation by the USA, it would conduct a nuclear test to confirm its nuclear status. North Korea reported a successful nuclear test on October 9, 2006 (see?2006 North Korean nuclear test). Most U.S. intelligence officials believe that North Korea did, in fact, test a nuclear device due to radioactive isotopes detected by U.S. aircraft; however, most agree that the test was probably only partially successful.?The?yield?may have been less than a?kiloton, which is much smaller than the first successful tests of other powers; however, boosted fission weapons?may have an unboosted yield in this range, which is sufficient to start deuterium-tritium?fusion in the boost gas at the center; the fast neutrons from fusion then ensure a full fission yield. North Korea conducted a second, higher yield test on May 25, 2009

Israel is not a member of the?Nuclear Non-Proliferation Treaty?and refuses to officially confirm or deny having a nuclear arsenal, or having developed nuclear weapons, or even having a nuclear weapons program. Israel has pledged not to be the first country to introduce nuclear weapons into the region, but is also pursuing a policy of strategic ambiguity?with regard to their possession. Israel may have tested a nuclear weapon along with?South Africa?in 1979, but this has never been confirmed
