Yeah, that was the "official" reason, but just use a bit of common sense, and it doesn't add up. If you have ground breaking technology that's vastly superior to anything else on the planet, you don't just just scrap it including all documents and classified information, because you have a hunch there might be a Russian mole. That's why until this day, there's still speculation as to why the project was actually scrapped. It's widely believed the US forced Canada's hand, took the technology for its airforce, and forced Canada to completely destroy the project.

As for Christian's comment about the best engineers in the world again. Which company was it that helped computerize and catalougue all those Jews in the camps ready for chemical extermination? Oh right, that would be IBM, a US based company.

Anyway, back to the OP. China is quite obviously kicking ass, and taking names, and there's nothing anyone can do to stop them. In the meantime, you have the EU holding on by the skin of its teeth, and Trump running the US into the ground at a very impressive pace. He's definitely the best, but just wrong direction dude.

Due to investments in renewable energy, China is planning to generate 13,000,000 new jobs by 2020, and a decent portion for that decision was because Trump pulled out of the Paris Accord and doesn't believe in climate change. So I guess Trump is making good on his pledge to generate millions of new jobs, but wrong country you fucken imbecile!
