But couldn’t Saudi Arabia simply buy a nuclear bomb? That’s highly unlikely. Any such effort would have to take place secretly, under the threat of sanctions, Western retaliation and interception. Saudi Arabia depends heavily on foreigners and their firms to help with its energy industry, build its infrastructure, buy its oil and sell it goods and services. Were it isolated like Iran or North Korea, its economic system would collapse.
It is often claimed that Pakistan would sell nukes to the Saudis. And it’s true that the Saudis have bailed out Pakistan many times. But the government in Islamabad is well aware that such a deal could make it a pariah and result in sanctions. It is unlikely to risk that, even to please its sugar daddy in Riyadh. In April, Pakistan refused repeated Saudi pleas to join the air campaign in Yemen.
So let me make a prediction: Whatever happens with Iran’s nuclear program, 10 years from now Saudi Arabia won’t have nuclear weapons. Because it can’t.
