President Trump’s behaviour at the latest press conference was disgraceful. Not knowing which World War you are talking about, out of two choices, is just trivial and embarrassing.

The real concern is with his treatment of the Secret Service. When they request you to leave a meeting, it’s not because they want a coffee break, but it’s because you are in danger and they are in even more danger because they are going to be standing between you and any potential attack. You do whatever they say.

It’s time to start treating people with more respect, Mr. President.
