U.S. signed a nuke deal with N Korea; then violated it

"In 1994, the Clinton administration and North Korea signed an Agreed Framework that froze Pyongyang’s nuclear programme and aimed to normalise US-North Korean relations. The agreement targeted many of the issues that the two sides continue to grapple with – but it soon ran into problems, and ultimately broke down in 2002." "But on its own pledges, Washington failed to follow through."
