In his interview with CNN, Biden also criticized the administrations diplomatic tack toward North Korea as not advancing U.S. interests and failing to extract sufficient concessions from leader Kim Jong Uns nuclear-ambitious regime.
Trump last week became the first sitting U.S. president to foot in the isolated, communist state, with the aim of launching a new round of arms control negotiations with Kims government.
He gave Kim everything that he wanted: legitimacy, Biden said, charging that Trump ended our relationship as a practical matter with Japan and South Korea and pierced the united front shared by the U.S. and the democratic Asian nations.
Biden claimed that Kim hasn't done a thing to take concrete steps toward denuclearization, and pledged as president to demand greater accountability from Pyongyang before relieving any economic penalties.
I'd make it real clear: Look, you want to talk, you want to deal with us, you want sanctions lifted? Show me something ahead of time. Show me. Biden said, adding: They're sitting there with missiles that have capacity and nuclear capacity right now. So they're not giving up anything.
