The deal would provide a nuclear and missile test moratorium on North Korea in exchange for food aid. Reuters
reports that after the rocket launch, the food aid offer was withdrawn.
says that last Friday's rocket launch in North Korea was condemned by the UN Security Council (UNSC) and is widely regarded as being a cover up to test a long range nuclear missile.
On Tuesday, Pyongyang responded in anger at the UNSC for violating the country's right to put satellites into orbit.
In a statement delivered by the official KCNA
news agency, Pyongyang said: "We resolutely and totally reject the unreasonable behavior of the UNSC to violate (our) legitimate right to launch satellites."
The statement further read that Washington was attempting to rob Pyongyang of its right to conduct space research:
quoted the following statement:
"As the US violated the February 29 [North Korea-US] agreement through its undisguised hostile acts, we will no longer be bound to it."
North Korea now considers itself free from the original agreement and says it has "become able to take necessary retaliatory measures." What these retaliatory measures will be was not stated.
Analysts suspect that with its third test, North Korea will attempt development of a nuclear device using highly enriched uranium. It has long been suspected that the country was developing this, but it was only admitted publicly around 2 years ago.
According to Baek Seung-joo of the Seoul-based Korea Institute for Defence Analysis
: "If it conducts a nuclear test, it will be uranium rather than plutonium because North Korea would want to use the test as a big global advertisement for its newer, bigger nuclear capabilities."
Experts state that if North Korea successfully enriches uranium, which can be used to make bombs of the type dropped on Hiroshima almost 70 years ago, the country would be able to build up significant stocks of weapons-grade nuclear material. This would also make the manufacture of a nuclear warhead to mount on a long-range missile possible.
