Iran has been accumulating nuclear material and armaments from various other nations (Russia, and China mainly) over the last decade (as reported in CIA annual reports to the President on the Global Threat Level when they were still available publicly), so the U.S. Gov't and Intelligence Community has known about the potential nuclear threat posed by Iran for a many years. While I have come to believe in the need for a more domestically focused policy to both repair and ensure the prosperity of our Nation (as in, we need to start minding our own & less actively poking our collective nose in other country's daily business, as our historical policy of having done so has caused the U.S., and Americans to be poorly portrayed by global media, and therefore, the citizens of other countries have developed such active anti-American sentiment), the Middle East region, and in particular, the country of Iran is so politically volatile, and holds such active anti-US sentiment, that we as a Nation and a Global Power, would be completely negligent of our Nation's long-term survival and safety, if we fail to acknowledge, or to proactively act upon the immediate or long term high level of threat which the country Iran posses to the U.S. and Western civilization. With the existence of long range surface to ground missile capability in the hands of countries in Asia (China and I believe one report stated N.Korea), who currently enjoy close trade relations, and who have a history of supplying armament and nuclear weapon components to Iran, the U.S. must not ignore Iran's determination to possess armament that can directly strike our Nation. Not only is the likelihood of Iran's possession of nuclear armament an issue, but even more so, is the religious zealotry and targeted anti-American, anti-Western civilization, ideology that Iran is actively indoctrinating not only its own citizens, but is is spreading its ideology and anti-US threat globally, with the active goal of eliminating the US and Western Civilization as a whole. The U.S. has never, not even against the spreading of the Communist threat, faced such an insidious and damaging threat as that of the Middle Eastern 'jihad' ideology, in which Iran is deeply and actively steeped. We as a Nation, can not fail to act against Iran, because if we do, we as a Nation and civilization, face the all too real and likelihood of elimination by another country's ideology and actions.
