I think it’s pretty safe to assume that the Chinese and Russians have all of our technology. Whether or not they can mass-manufacture it is another story, but that’s small comfort.

Washington (AFP) – A US Hellfire missile has turned up in Cuba after going missing in a fiasco that has left American officials worried the technology may be shared with China, Russia or North Korea, the Wall Street Journal reported.

Though the missile was not carrying a warhead, the alarming diversion while it was in transit from Europe has spurred US investigators to probe whether its arrival on the communist island was the result of criminal activity or merely a series of mistakes, according to the newspaper.

And despite a historic thaw in ties with Cuba over the past year, Washington has been unsuccessful in its push to get the missile back, the WSJ said, citing unnamed sources.

It reported that American officials were not concerned that Cuba would take apart the Hellfire — an air-to-ground missile often carried by helicopters — but were worried that Havana would share the technology with US rivals China and Russia, as well as North Korea.
