Qatar was part of the recent coalition assembled with Saudi Arabia and others in the region... before Saudi accused Qatar of supporting terror. (I already posted that Qatar plays both sides of the street, as if Saudi Arabia is completely clean). President Trump made a comment in support of the Saudi criticism, but not supporting the breakup of the coalition. That's money they can't give to terrorists. We have major air base(s) in Qatar in regular use, so benefit from working with them.
Iran has just flown 100 tons of food to Qatar breaking the Saudi blockade and weakening the US formed coalition. Sorry I couldn't find news reports about a new Trump tower there? Apparently Qatar airways is tenant of trump Tower in US.

PS: Two men in US (one from michigan other from NYC) were just arrested for working with Hezbollah to scout and plan future terror targets in US and Panama. This seems pretty real and serious.
