The problem is not firepower, it is identifying legitimate targets. Have you got a new sensor that can identify the intensions of an individual? All the firepower in the world will not do you a bit of good if you cannot find your targets.
Retaliation raids against what targets on the mainland? Are you going to be targeting civilians? Because all the military targets will be disbursed among them.

What you describe here is the NEW method of warfare where propaganda and world opinion have become the weapon of choice. For this to be successful you have to convince the world that your civilians are worth saving, and the attacking country has to care about world opinion. Israel is currently in a middle ground on these types of propaganda attacks. Israel doesn't seem to particularly want to care about the world opinion, but the pressure against them is mounting and the tactics have begun to work.
In a fight with Iran, it will again depend on world opinion and you can expect to see the heart felt stories of injured children and wailing women to help turn your support for the peace loving Iranian underdog against the war mongering United States and her allies. This is one reason why it is important to the U.S. that Iran fire first, if an engagement does occur. It is Iran's actions leading up to that war shot that will determine the level of sympathy many will have for them.
If the world becomes angry enough at Iran, then support will be harder to sway when the inevitable images of civilian casualties start showing up on CNN and Al Jazeera. No weapon is accurate enough to hit targets buried next to hospitals and schools without causing civilians deaths. I would not put it past the fanatical Iranian to intentionally stand near such targets at an attempt at martyrdom so their death CAN become a political weapon in the media.
Still, I feel the chance of engagement can be avoided even still. Iran needs to abandon enrichment and accept the offer of reactor fuel from a friendly state, like Russia or China. I do not believe the west is worried about nuclear power plants in Iran, just the enriched uranium that can be easily moved, easily not recorded, and easily "lost". The average Iranian civilian needs to realize though that uranium has a specific footprint and if used as a weapon anywhere, it WILL be traced back to them and the consequences will be tragic as they will have lost all credibility for the future justification of their nuclear program.
Sure, it's not fair that several countries already have nuclear enrichment programs and nuclear weapons. However, for the world to ever get rid of these weapons, we must restrict proliferation, not expand it. The United States and the Russian Federation have been reducing their stock piles significantly, though they still have a ways to go. France announced they will reduce the number of air delivered warheads by a third, and the UK is reducing their nuclear armory by about 40 warheads. How can these countries justify their reductions if the threat of nuclear attack is going up, not down?
