Saber-rattling continues from Israel and elsewhere, but we meanwhile have another apparent technological challenge to Iran’s nuclear development plans. Iran has accused the German technology company Siemens of planting tiny explosives inside equipment Iran bought for its disputed nuclear program, a charge Siemens denied. Aladdin Boroujerdi, a prominent lawmaker, said Iranian security experts discovered the explosives and removed them before detonation. Stuxnet, a computer virus that damaged Iran’s uranium centrifuges in 2010, also was based on attacking Siemens equipment.
