The Iraq war is finally over. And it marks a complete neocon defeat

Their hopes of making Iraq a democratic model for the Middle East have been tipped on their head. The instability and bloodshed which the US unleashed in Iraq were the example that Arabs sought to avoid, not emulate. This year's autonomous surge for democracy in Egypt and Tunisia has done far more to galvanise the region and undermine its dictatorships than anything the US did in Iraq. And when the Arab spring dawned, the Iraqi government found itself on the defensive as demonstrators took to the streets of Baghdad and Basra to protest against Maliki's authoritarianism and his government's US-supported clampdown on trade union activity. Maliki hosted two Syrian government delegations this summer and has refused to criticise Bashar al-Assad's shooting of protesters.

But the neocons' biggest defeat is that, thanks to Bush's toppling of Saddam Hussein, Iran's greatest enemy, Tehran's influence in Iraq is much stronger today than is America's. Iran does not control Iraq but Tehran no longer has anything to fear from its western neighbour now that a Shia-dominated government sits in Baghdad, made up of parties whose leaders spent long years of exile in Iran under Saddam or, like Sadr, have lived there more recently.
