Last week one of America's top uniformed officers General James Cartwright in front of the Senate came to the conclusion that the United States would not be able to stop Iran permanently from developing nuclear weapons unless it was willing to occupy the country.
Senator Jack Reed a democrat from Rhode Island then went on to ask if the only way to end any potential Iranian nuclear weapon development "was to physically occupy their country and disestablish their nuclear facilities?"
Cartwright responded by stating that: "Absent some other unknown calculus that would go on, that's a fair conclusion."
Such speculation and 'hype' over a US attack on Iran has raised from leaked memo from Secretary of Defense Robert Gates which details what actions to take against Iran's nuclear programme if it proceeds regardless of the international sanctions.
On an interview on Fox News over the weekend Senator and former Republican presidential nominee John McCain stated "We [the United States] have not done anything that would in any way be viewed effective. I didn't need a secret memo from Mr Gates to ascertain that."
McCain has further asserted that:
"We keep pointing the gun, we haven't pulled a single trigger yet, and it's about time that we did."
However with all of the media hype Admiral Mike Mullen the chairman of the Joint Chiefs of Staff has stated a military strike would be 'his last option' and has warned of the unintended consequences of such a strike.
But he also agreed that the UN sanctions would not be tough enough to have a serious impact on Tehran.
Iran's current level of enriched uranium is 3.5%, 90% and over is the amount used in nuclear weapons, the government in Tehran continues to assert it's nuclear enrichment program is for peaceful purposes and that they are not seeking to build a nuclear bomb.
