Saudis are buying nuclear-capable missiles from China DEBKAfileâ€™s military sources report that Saudi Arabia has set its feet on the path to a nuclear weapon capability and is negotiating in Beijng the purchase of Chinese nuclear-capable Dong-Feng 21 ((NATO-codenamed CSS-5) ballistic missile. China, which has agreed to the transaction in principle, would also build a base of operations near Riyadh for the new Saudi purchases. As we reported last year, Saudi Arabia has struck a deal with Pakistan for the availability on demand of a nuclear warhead from Islamabadâ€™s arsenal for fitting onto a ballistic missile. Riyadh owns a direct interest in the two most active Middle East issues: Iran and Syria. Iranâ€™s nuclear weapons program has been advancing for two decades regardless of countless attempts at restraint by every diplomatic tool under the sun and a rising scale of sanctions â€“ to no avail. Tehran marches on regardless of impediments. In Istanbul, Tuesday, July 3, the six powers and Iran failed the fourth attempt to reach an accommodation on Iranâ€™s nuclear program. The Syrian ruler Bashar Assad remains equally undeterred by international condemnation. Saturday, June 30, the US and Russia again failed to agree on a joint plan of action in Syria. Saudi forces have been poised for action in Syria on the Jordanian and Iraqi borders since US Secretary of State Leon Panetta visited Riyadh in late June. On July 1, they redoubled their military preparedness when the European Union clamped down an oil embargo on Iran. The Saudis, the US Fifth Fleet and the entire Gulf region are since braced for Iranian reprisals which could come in the form of closure by Tehran of the vital Straits of Hormuz to shipping or strikes against the Gulf emiratesâ€™ oil exporting facilities. Tension shot up again when Iranâ€™s Revolutionary Guards launched a three-day missile drill against simulated enemy bases in the region â€“ expanding its threats to include US forces and bases in the region, Israel and Turkey.
