Buying Goods To Make Nuclear Weapons On eBay, Alibaba, and Other Platforms
Lasrick (2629253) writes The blossoming of online Internet-trading platforms has at least one downside: insufficient inspectors and product controls when it comes to goods relevant to nuclear proliferation. "On Alibaba (and other platforms), one can purchase many of the specialized items needed for the manufacture of nuclear weapons. A short list of items advertised for sale on the site include metals suitable for centrifuge manufacturing, gauges and pumps for centrifuge cascades for uranium enrichment, metallurgical casting equipment suitable for making nuclear weapon 'pits,' and high-speed cameras suitable for use in nuclear weapon diagnostic tests. A company on an Alibaba-owned Chinese Internet-trading platform even posted an ad for the sale of the rare metal gallium, which the seller trumpeted could be used to stabilize plutonium." Although many companies have strict compliance procedures in place to help avoid proliferation, many do not. There are several procedures these platforms can put into place to minimize risk, and both national (and international) regulators have a role to play, as well as shareholders.
NOT making nuclear weapons...
Sorry, this is pretty much BS scaremongering.
Buying a piece of metal that could be made into a centrifuge doesn't mean that you will actually succeed to make one. There is a lot of specialized equipment needed for that which is tightly controlled (try to export a high precision CNC machine, for example!).
Most of this gear has lots of legitimate uses as well. Not to mention that if someone really wanted to obtain this sort of gear, I cannot imagine them shopping for it on Alibaba or eBay - they would be spending a ton of money for a product of unknown quality possibly from a mom&pop shop somewhere in China that sells everything from rubber bands, dresses up to car accessories, that is assuming it isn't a scam in the first place. There are better ways of obtaining it - e.g. through shell companies abroad acting as middlemen to avoid embargoes or from friendly nations.
And before someone pulls out the "terrorist building nukes" bogeyman - that requires a lot more than building a few centrifuges from stuff bought on Alibaba. There are plenty of simpler, cheaper and easier accessible methods to wreak havoc than trying to build a nuke that even countries like Iran didn't succeed in so far, despite vastly bigger resources than some lunatics in a cave possess.
