You missed my point. It's really not about stopping the Iranian program, it's just about not looking like a wimp.
On symbolic actions consider the Iraq war. The unshocking Shock N Awe of the initial assault, which was a pale shadow of Desert Storm. Fallujah#1, no military purpose, directly against Gen. Conway's counsel, aborted for political reasons. Falliujah#2: An assault delayed by a month for the US election allowing the enemy to slip away. Rummies failure to transform the tech heavy US military for grunt intensive 21st century neo-colonial operations. The kinetic big sweep operations in the western desert. I could go on, an endless list of actions that cultivated US domestic opinion rather than victory.
Look at their record, these people do mostly symbolic lite warfare and waffle like girl scouts about liberation. Lacked the nerve to chase Bin Laden into Pakistan, failed to destroy the Iraqi army in the field. I'm afraid that's the problem is these people aren't Kissinger or even Poppy Bush. They may actually be better more moral people than bad old Henry but they are plain hopeless at convincingly resolute warfare.
