Does he ever have any clue of what he does with any domain?
In fact, it appears that he'll get the exact opposite of what he expected (if he ever anticipated anything ).

When he was doing The Apprentice, he was being chauffeured in a Maybach for many episodes. I think it's more of a ruse to rile up his supporters into thinking the "evil" Germans are stealing the auto industry. He has no clue what he is doing with international trade.

He really doesn't like german cars. I wonder why. Did something happen when he was younger ? Did he burn his very very strong and large fingertip with the cigar lighter of a Mercedes ? Did he stuck his luxuriant hair in the sunroof of a BMW ?

Here is how Mr. Trump is complaining about German's car export at Germany's car exports to America have been falling for years.
