The US Must Aim at Toppling Down the Regime
Iran seeks to lead the Middle East system religiously and politically. It endangers world system with grave consequences to US interests, which symbolizes the march of fanatic Islam. The US must consider seriously using military force - not against Iran's nuclear sites, but aiming at toppling down the regime. Iran's internal surroundings permit us to believe it is possible.
Iran is “the biggest Satan”; the epitome of evil, in its ambitions to purchase nuclear weapons and rule over the Arab Middle East. It is now the imperial revisionist power aiming at controlling the Middle East system. If there is a belief that one can come to terms with Iran without nuclear weapons and without changing the balance of power in the region, it comes from a deep illusion and basically does not understand contemporary Iran. It is moved by deep religious beliefs and 1400 years of materialized frustrations. The purpose of Iran's revisionism is to be fulfilled and accomplished. Its leaders really do believe that they can do it – they can end the Sunni superiority and change the course of history by remaking and establishing the supreme justice – the Shiites (Shi`at `Ali) deserve the Islamic leadership; that they are entitled to lead Islam.
This is the reason that the US cannot come to terms with Iran. This leaves fighting back as the only alternative. The US must stop Iran’s onslaught doing all that is necessary to cut off Iran’s expansionist ambitions, bringing it to reality by effective military deterrence.

If anything we should strike Isreal in retaliation for the unprovoked attack on the USS Liberty.
Considering the effort US interests put into establishing Isreal and the effort US interests put into exploiting Iran, I really fail to see the moral imperative here.
Maybe if Isreal would stop raiding villages in areas it deems itself worthy to govern it would have the resources to topple Iran itself.
Or maybe, if we take a breath and get a clue, we might give the people there a chance to take matters into their own hands and topple their own tyrants.
Why Should the US risk it's soldiers and wealth to protect Israel? To each country their own.
We've already shown that we are a failure when it comes to regime change--why tangle with a larger, stronger country?
Yes, *both* military and ideological attack must be used against Iran, the "motherland" of Islamic totalitarianism. There can be no compromise, no diplomacy or "talks" with an enemy dedicated to your destruction, and who has already attacked you. Iran's attack began with the hostage-taking in '79 and continues to this day in its sponsoring, supplying, and guiding the attacks on our soldiers in Iraq.
We already *are* at war with Iran.
