Sources: Saudi Arabia could obtain nuclear weapons from Pakistan "at will"

While the kingdom’s quest has often been set in the context of countering Iran’s atomic programme, it is now possible that the Saudis might be able to deploy such devices more quickly than the Islamic republic.

Earlier this year, a senior Nato decision maker told me that he had seen intelligence reporting that nuclear weapons made in Pakistan on behalf of Saudi Arabia are now sitting ready for delivery.

Last month Amos Yadlin, a former head of Israeli military intelligence, told a conference in Sweden that if Iran got the bomb, “the Saudis will not wait one month. They already paid for the bomb, they will go to Pakistan and bring what they need to bring.”

Since 2009, when King Abdullah of Saudi Arabia warned visiting US special envoy to the Middle East Dennis Ross that if Iran crossed the threshold, “we will get nuclear weapons”, the kingdom has sent the Americans numerous signals of its intentions.
