Its known and documented in intelligence reports Saudi government supports terrorists. Here's a quote from one of intelligence reports, "it was well-known in intelligence circles that the Islamic affairs office functioned as the Saudis’ ‘fifth column’ in support of Muslim extremists."

9/11 commission report documented the terrorists meeting with Saudi intelligence officers on US soil and they were partly funded by Saudi royalty. Also lets look at Pakistan. They were harboring Osama Bin Laden.

I don't disagree, but the chaos from Trump declaring Saudi Arabia, a current strategic ally in the region both for material resources and military cooperation, would be on a scale that no one here would like to pick up the pieces from.

We deal with a lot of countries around the world that do things we don't like, we don't have to like it, but diplomacy and politics are messy and require compromise in situations where it's a better choice versus the alternative.

Round and round you go with circular logic and rationalizations. This is at best security theater and a dumb executive order designed to appeal to emotion rather than reason. That's putting aside any ethical considerations. You can keep trying to sell it, but nobody with a brain is buying it.

Banning Iran, Boeing will probably lose a $16 billion contract over it. Ban doesn't seem to be well thought out.

How does banning Iranians from coming over fight state sponsored terrorism? Has there been a single instance of an Iranian traveling or immigrating to the US and committing an act of terrorism?

ooooooooookay.
