I think negotiators from all countries and their leaders just arent used to dealing with someone like trump/team especially from US side.They asked for it by even agreeing to a deal in the first place. Trump loves bullying and exploiting people who show weakness.
Some think if they agree fast that will appease him and wont get a 'bad deal' but then they get squeezed cause he smells weakness.
Some think keep doing many many meetings and keep giving more and more away, end result is the same,
Few stand up and do a 'tough' negotiation and get something amicable back.
The old style thinkers and policy people seem to be all stumped, or they do know but they are saving their careers by not saying the obvious truth.
Is because He wants TSMC to bailout intel with 49% purchase..??
