retired rear admiral john kirby, spokesman for the state department. put on your military hat for a moment. is it appropriate for the president of the united states to salute a foreign general, let alone a foreign general of a regime like north korea? >> no, it's not. the very valid concern here was he was showing deference and respect to an officer in the military who not only brutalizes their own soldiers but their own people and still have a robust military program capable of destabilizing the region. then there is the propaganda value. if shouldn't be a surprise to anybody that north korean state tv is airing this thing on a constant loop. it's cannotexactly the image an respect that kim jong-un was trying to seek. >> so would it be appropriate for the president to salute a british or french general as opposed to a north korean general? >> look, there is not strict protocol on this.
