He would run a child's lemonade stand into the ground.

Trump attacked iran in the middle of negotiations. It's probably a pattern from the salesmen book he didn't even write.

That should read, Trump betrays Americans. The reality is that he is destroying American credibility on the international stage, which is going to have long term effects on their ability to make agreements with other countries in the future. Standing alone is not in the interest of any nation.

As for betraying Canadians, Trump is not responsible for representing Canadian interests. I wouldn't want him to either. (Speaking as a Canadian.)
