Well, that would take two parties. Actually, two parties who wanted a peaceful solution. Trouble is, one wants peace and one does not.

This is simply not true. If Iran didn't want peace, they would not have offered to negotiate. Part of the reason the people of Iran voted Ahmadinejad into power was because the previous president was undermined by the Bush administration when it rebuffed Iran's offer to negotiate. Under the circumstances, Iran has legitimate reasons to be concerned about its security. Iran offered to negotiate and the US refused. That is, in itself, an indication of an intent on the part of the US to commit acts of aggression against Iran.

Ahmadinejad is only the president. He doesn't call the shots. The US needs to support the more moderate factions in Iran by being willing to negotiate with the government of that country. It didn't do this because it serves the strategic objectives of both the US and Israel for the most extreme elements to be in power in Iran because what they want is to create a pretext for waging a unilateral attack on that country. The US and Israel don't want security. They want hegemony in the region, regardless of how many people have to get killed in the process.
