What an arrogant, naive, foolish, and completely ignorant thing for a president-elect to refuse to do. He should be in these meetings every day learning about potential threats and how the world works!
Today he took a call from Taiwan, without consulting anyone. Something that hasn't been done since the 70's! This is a right he doesn't have as president-elect. Apparently he's preoccupied with his "thank you" tour and simply doesn't care to understand the job.
