Predicting that sanctions will ultimately fail to stop Teheran's nuclear program, Brig.-Gen. (res.) Yossi Kuperwasser... told The Jerusalem Post on Monday that time to launch an effective military strike against Iran's nuclear installations was running out... Kuperwasser, who stepped down from his post last year, Iran is "very close" to the point that it will cross the technological threshold... "The program's vulnerability to a military operation is diminishing as time passes," Kuperwasser said, "and they are very close to the point that they will be able to enrich uranium at an industrial level." Iran... was working on two parallel tracks - one at Natanz to enrich uranium and the plutogenic track being worked on at the Arak heavy water facility... "The Iranians are working around the clock on improving military capabilities and they are also moving centrifuges to underground facilities," he said.

As long as Russia was not aligned with the United States, Kuperwasser said sanctions would not work on their own to stop Iran. "For significant sanctions to be effective the world needs to at the same time threaten the use of military force," he said.
