There's the plan – and then there are the unintended consequences. The United States talks diplomacy, then bombs Iran. It suggests the targeting of nuclear sites may have been a one-off, yet leaves the regime uncertain: is regime change the real objective? Following its most significant show of force since the invasion of Iraq, will Washington take ownership of what comes next? For now, the US asserts itself as the sole superpower capable of projecting force in a region where China appears reduced to the role of chief oil customer, and Russia remains preoccupied with Ukraine. And with Israel now striking Tehran's notorious Evin Prison, it's clear this goes far beyond nuclear ambitions. We look at the options left to a weakened Iran – and the consequences of toppling a militarised theocracy.
