I argue, as I did with the Libyan intervention, that the United States should not be limited by the UN Charter, which limits the use of force to self-defense or when authorized by the Security Council (which would never approve strikes against Iran because of China’s and Russia’s vetos). The Charter rules have never described state practice and have the effect of keeping dictators in power and preventing the United States and its allies from maintaining peace and security in the world. The United States should have the legal right to use military force when it removes dangerous threats not just to our security, but to regions and the world — and that is, I argue, exactly what is posed by the prospect of Iranian nuclear weapons.
