Can anything be more moving than the joyous throngs swarming the streets of Baghdad? Memories of the fall of the Berlin Wall, and the defeat of Milosevic in Belgrade flood back. Statues and images of Saddam are smashed and defiled. Liberation is at hand. Liberation — the powerful balm that justifies painful sacrifice, erases lingering doubt and reinforces bold actions. Already the scent of victory is in the air. Yet a bit more work and some careful reckoning need to be done before we take our triumph.

Still, the immediate tasks at hand in Iraq cannot obscure the significance of the moment. The regime seems to have collapsed — the primary military objective — and with that accomplished, the defense ministers and generals, soldiers and airmen should take pride. American and Brits, working together, produced a lean plan, using only about a third of the ground combat power of the Gulf War. If the alternative to attacking in March with the equivalent of four divisions was to wait until late April to attack with five, they certainly made the right call.

But no one ever won a war or a battle with a plan. Every soldier knows there are only two kinds of plans: plans that might work and plans that won’t work. The art of war is to take a plan that might work and then drive it to success. This, General Tommy Franks and his team did very well indeed.

But the operation in Iraq will also serve as a launching pad for further diplomatic overtures, pressures and even military actions against others in the region who have supported terrorism and garnered weapons of mass destruction. Don’t look for stability as a Western goal. Governments in Syria and Iran will be put on notice — indeed, may have been already — that they are “next” if they fail to comply with Washington’s concerns.

As for the political leaders themselves, President Bush and Tony Blair should be proud of their resolve in the face of so much doubt. And especially Mr Blair, who skillfully managed tough internal politics, an incredibly powerful and sometimes almost irrationally resolute ally, and concerns within Europe. Their opponents, those who questioned the necessity or wisdom of the operation, are temporarily silent, but probably unconvinced. And more tough questions remain to be answered.

Is this victory? Certainly the soldiers and generals can claim success. And surely, for the Iraqis there is a new-found sense of freedom. But remember, this was all about weapons of mass destruction. They haven’t yet been found. It was to continue the struggle against terror, bring democracy to Iraq, and create change, positive change, in the Middle East. And none of that is begun, much less completed.
