The other deal cut with the Saudis at the same time was that Boeing also said it would negotiate the sale of up to 16 widebody airplanes to Saudi Gulf Airlines which is based in the country's east in Dammam.  

 That is in addition to the Chinook helicopters and P-8 surveillance airplanes.  

Of course, the US could have decided to let the European Union's Airbus  or Russia's Tupolev  provide those civilian aircraft.  That would have shown them!

I suspect that the two Democratic Senators and Democratic Governor in Washington State will prefer the current deals, however.  The taxes will be paid, whether there is any 'trickle down' to the machinist's union or not.
