P.S. From the comments at Bayou Renaissance Man:
We talk and worry about all kinds of technological hijinks – but something as simple as mis-marking measuring tapes could cost another country millions in lost productivity. Partnering with competitors or enemies for ANYTHING is more than a questionable strategy. Lessons learned in the schoolyard still apply.
