SEOUL - North Korea has bolstered its defenses against a "hostile" United States with its third nuclear test, it said on Thursday, noting that countries that had bowed to US pressure to abandon their nuclear plans had suffered "tragic consequences".
The North carried out its largest nuclear test to date last week, in defiance of UN resolutions, prompting warnings of tougher sanctions for the isolated and impoverished state and its young ruler, Kim Jong-un.
Libya abandoned its nuclear program in 2003 in a bid to mend relations with the United States and later saw leader Muammar Gaddafi overthrown in an uprising that was eventually supported militarily by Washington.
In apparent reference to Libya, North Korea said it never backed down.
"The tragic consequences in those countries which abandoned halfway their nuclear programs... clearly prove that the DPRK (Democratic People's Republic of Korea) was very far-sighted and just when it made the (nuclear) option," North Korea's KCNA news agency said.
