I do have some tips for him, though, that hopefully will help.
1. When negotiating, don't rely on Michael Cohen for assistance. His track record hasn't been too good lately, and I suspect North Korea will have higher standards than a porn actress. (And besides, he's probably pissed off that he hasn't been reimbursed yet for that $130,00.)
2. Don't rely on getting good advice from the U.S. ambassador to South Korea. We don't have on.
3. Don't rely on any advice from the State Department's expert on North Korea, Joseph Yun. Hopefully he left a forwarding number in case there are any questions.
