Iran's danger

Reality Check: Shorter and Shorter Timeframe if Iran Decides to Make Nuclear Weapons - David Albright, Paul Brannan, Andrea Stricker and Andrew Ortendahl
Some have sought to downplay Iran's nuclear progress by emphasizing that Iran has not yet "made the decision to build a nuclear weapon." But this does not accurately portray the real concern about Iran's nuclear program and progress since Iran has already made a series of important decisions that would give it the ability to quickly make nuclear weapons.
    Iran's strategy of "nuclear hedging," or developing the capability to rapidly build nuclear weapons under the cover of a civilian nuclear program, is laid out in the evidence of work on nuclear weaponization, particularly efforts to make specific nuclear components, contained in the November 2011 International Atomic Energy Agency (IAEA) safeguards report on Iran. If Iran's ability to quickly build nuclear weapons increases during the next few years, this will only shorten the period of time between taking a decision to build a bomb and constructing one.

The Mortal Threat from Iran - Mark Helprin
Without doubt, Iran has long wanted nuclear weapons - to deter American intervention in its and neighboring territories; to threaten Europe; to respond to the former Iraqi nuclear effort; to counter the contiguous nuclear presences in Pakistan, Russia and the U.S. in the Gulf; to neutralize Israel's nuclear deterrent; to lead the Islamic world; to correct the security imbalance with Saudi Arabia; and to threaten the U.S. directly. In the absence of measures beyond pinpoint sanctions and unenforceable resolutions, Iran will get nuclear weapons, which in its eyes are an existential necessity.
    Accommodationists argue that a rational Iran can be contained. Not the Iran with a revered tradition of deception; that during its war with Iraq pushed 100,000 young children to their deaths clearing minefields; that counts 15% of its population as "Volunteer Martyrs."The writer is a senior fellow at the Claremont Institute. (Wall Street
