Not true any longer, we (the usa) have exported most of our tech, and most of our manufacturing. The Euros (plus the Japanese and soon Chinese) are just as capable as us.
Being an ex-Bae employee. I can tell you there are very few American aircraft flying today which does not have British technology integrated at the design stage. A prime example being the F35. And when China becomes THE world superpower, you and the Brits will be requesting Chinese export licenses.
