That's a big stretch. The truth is, all previous administrations have been weak on Saudi Arabia.
And yes it should be on the list too. Mainly because Saudi Arabia has the US on its list. No American who isn't Muslim will ever be allowed to emigrate to Saudi Arabia. It's only fair that unless Saudi allows Americans to emigrate as Christians, atheist etc. then the US shouldn't allow anyone from Saudi to settle in the US.
The countries banned are the same countries the Obama administration deemed dangerous. Trump literally just copy/pasted Obama's own list and later added Venezuela and NK when these countries went full retard too.
Think about what the means for a second. Obama supporting Democrats LITERALLY think people from dangerous countries should come to the US as they please, just like any other migrants or tourists.
