An All Too Common Natural Occurrence In That Industry.

Some people in Britain actually complained when Thatcher made sure they never had to do Coal Mining ever again.

I don't think anyone ever doubted Israel's ability though. As long before Stuxnet you had the Cornstarch explosions.

It turns out that Uranium Enrichment Centrifuges, such as those at Iran's Natanz underground lab, are extremely complicated, delicate pieces of equipment. 

Meaning you need to wear Latex gloves when handling any component. You need to use Cornstarch to lubricate those Latex gloves. So you can take them on and off.

Legend has it that Iran put in a bulk order for Latex gloves lubricated with a certain grade of Cornstarch. Only for Israel to infiltrate the supply-chain and replace the ordered gloves with gloves lubricated with an ever so slightly coarser grain of Cornstarch.

Those ever so slightly larger grains of Cornstarch was enough to jam the mechanism of the Centrifuges, causing them to explored.

Personally I thought that was just showing off.

Given that if you can get Electrons to march in the correct formations of "1" and "0." Then you can just turn the Cornstarch into a bomb.
