The campaign to prevent Iran from acquiring nuclear arms brings to mind a doctor who focuses on the symptoms while overlooking the disease. If Tehran is indeed building the bomb, it quest is a particular manifestation of a larger problem: nuclear proliferation.
The Iranian government is vulnerable to international criticism regarding human rights and can be pushed to reduce repression on its citizens, but its game of creating conflict, division and confusion has largely succeeded.
Implementing sanctions against Iran would play right into the hands of the theocracy. By imposing sanctions, the US will hand the Iranian government a card it does not have at this time--blaming the increase of prices on foreign powers.
A new nuclear fear grows in the hubris of our adventures in Iraq and Afghanistan and is compounded even further by some of our allies. Non-proliferation is not sufficient; complete disarmament is required.
