north korea threatening to banned summit. a member of the foreign affairs committee. always good to see you, congressman. >> you too. how are you? >> i'm doing well, thank god. so, are you shake anything your boots? is all lost now that north korea is saying we won't be put in a corner? we walk away first? >> no. they are probably doing a little bluster, trying to show his domestic population he is still in control. this is the old pattern of north korea. on the one hand, they come out smiling with unicorns they give to south korea. the next day it's like we're going to fight back and do all of this kind of stuff. i'm not losing sleep over this issue. it just shows north korea is back to their old pattern of give and take and angry and happy. that's always concerning because of what they've done in the past. >> jane harman was just on.
