How wrong was Trump?

I’m half Pakistanis & half Iranian. While I have a patriotic love for my origins; it’s hard to deny how disorganised Pakistan & Iran are (to varying degrees).

Obviously what Trump said was offensive however the fact that usually when a country has a diaspora, it means there’s something very wrong with it.

This is of course just my thoughts on the matter; it is offensive but how wrong is it? Is it offensive to tell the truth?
