"On September 19, 2005, the United States and North Korea signed an 'agreement in principle' that North Korea would give up 'all nuclear weapons and existing nuclear programs.' The agreement did not specify when or how this would take place. (See 'Proliferation Crisis in North Korea,' below.) On July 18, 2005, President Bush promised U.S. and international help to India to advance its civilian nuclear power program. Congressional action would be necessary before the transfer of technology and equipment could take place. (See 'India and Pakistan,' below.) On January 10, 2006, Iran informed the International Atomic Energy Agency (IAEA) that it would resume uranium enrichment research activities, heightening the possibility that its nuclear activities would be taken up by the UN Security Council. (See 'Iran's Nuclear Program,' below.)"
