You're clueless.
Boeing has partnered with foreign companies for decades. It is the only way, other than the government paying for it, Boeing can afford to develop a new aircraft.
Boeing has farmed out work over the years, for various reasons. Sometimes a sale to a State-owned airline, such as China, hinges on some of the work being thrown their way.
Sometimes it's a special project, like modifications to an existing aircraft in a small quantity (the 767 tanker and the 747 large cargo aircraft are examples).
But the majority of their planes were always made in the USA, until now. The majority of the 787 will be made overseas, on the order of 70-80%. With their new transport, they can farm out large assemblies, even entire fuselage sections. I expect this trend to accelerate.
If you don't see it, you are the one who's clueless.
I laugh when I hear someone say "If it's not Boeing, I'm not going!" Well, guess what? It's not Boeing.
Actually that would not have been the case formerly, back when the 747 was developed, for example. And it should not be the case today, but for the almost totally-subsidized AirBus "Competition", and the extortionate practices of countries playing off their "business" against Boeing and Airbus...demanding co-production contractions as part and parcel of their order...but for that, Boeing could charge as needed and tell the market countries that want co-production deals to "take a hike."
The downsizing of U.S. commercial production capacity has seriously hurt the ability of the U.S. to turn around and produce for war. I don't believe it prudent to rely for such production on nations that regard us as "the Main Enemy." I'm sure you know who I mean.
