Republican presidential candidate Mitt Romney writes in today's Wall Street Journal:
Successive American presidents, including Barack Obama, have declared [a nuclear Iran] to be unacceptable. But under the Obama administration, rhetoric and policy have been sharply at odds, and we're hurtling toward a major crisis involving nuclear weapons in one of the most politically volatile and economically significant regions of the world...
The United States needs a very different policy.
Si vis pacem, para bellum. That is a Latin phrase, but the ayatollahs will have no trouble understanding its meaning from a Romney administration: If you want peace, prepare for war.
I want peace. And if I am president, I will begin by imposing a new round of far tougher economic sanctions on Iran. I will do this together with the world if we can, unilaterally if we must. I will speak out forcefully on behalf of Iranian dissidents. I will back up American diplomacy with a very real and very credible military option. I will restore the regular presence of aircraft carrier groups in the Mediterranean and the Persian Gulf region simultaneously. I will increase military assistance to Israel and coordination with all of our allies in the region. These actions will send an unequivocal signal to Iran that the United States, acting in concert with allies, will never permit Iran to obtain nuclear weapons.
Only when the ayatollahs no longer have doubts about America's resolve will they abandon their nuclear ambitions.
Whole thing here.
