It explains that because of the legacy of the Korean War the US' adversarial relations with North Korea became a core element of overall US foreign and defense policy regionally and globally. The North Korean nuclear agreement brokered by China in 2005 at the six-party talks in Beijing represented progress for the US ambition of blocking the Democratic People's Republic of Korea's (DPRK's) nuclear weapons ambitions. The chapter discusses US adaptation of the Roh paradigm.
