KEY POINTS:
The British have given up and they know they will be leaving Iraq soon," said Moqtada al-Sadr, head of the Mehdi army, the country's most powerful militia group, in an interview with the Independent. "They have realised this is not a war they should be fighting, or one they can win."
Every word he said is true, and most senior officers in the British Army know it. As General Sir Richard Dannatt, head of the British Army, said last year, Britain "should get out [of Iraq] some time soon".
Being Prime Minister is hard. Gordon Brown waited 10 years for Tony Blair to pass on the prime ministership, and no sooner does he finally inherit the job than he has to figure out a way to pull the British troops out of Iraq in the middle of the American "surge". That will not be seen as a friendly gesture by the beleaguered Bush Administration.
There are 5500 British troops in Iraq, by far the largest foreign army after the Americans. But they control almost nothing except the ground they are standing on.
Some 500 of them are under permanent siege in Basra Palace. The rest are at the airport outside of town, under constant attack by rocket and mortar fire. They have almost no influence over the three rival Shia militias and the associated criminals who actually run the city and fight over the large sums of money to be made from stolen oil. Forty-one British soldiers have died in Iraq already this year compared with 29 in the whole of last year.
The deaths are wasted and it is high time to go home. But Mr Brown is reluctant to anger the White House by pulling all the British troops out before the Americans are ready to leave.
That, however, is unlikely to happen before President George W. Bush leaves office in January 2009, as British generals are well aware.
The Democrats in Congress have clearly decided that they prefer to see the Republicans go into the election late next year with the albatross of Iraq still tied firmly around their necks, rather than mount a congressional revolt, cut off funds for the war, and take the blame for the defeat.
Mr Bush says his policy is to "wait to see what David [Petraeus] has to say", when the commanding general in Iraq reports on what progress the "surge" is making in mid-September. But Mr Bush didn't fire the previous US commanders in Iraq and give Petraeus the job without knowing in advance what he would say. Petraeus will see light at the end of the tunnel, as he always does.
The Democratic majorities in Congress will criticise his report but not rebel against it, and US troops will probably stay in Iraq at roughly the present numbers until Mr Bush leaves office. Several thousand American soldiers will have to die, but so will around a hundred British troops.
British generals are deeply unhappy at this prospect, but as students of the indirect approach in strategy they have chosen to argue not so much that the war in Iraq is lost (though it is), but that the war in Afghanistan is still winnable. So the reason we must get British troops out of Iraq now is not just to avoid more useless deaths, but to win by reinforcing our commitment in Afghanistan, which is the truly vital theatre in the "war on terror".
General Dannatt was at it again last week, telling the BBC that "the Army is certainly stretched. And when I say that we can't deploy any more battle groups [in Afghanistan] at the present moment, that's because we're trying to get a reasonable balance of life for our people."
The too-frequent cycle of combat deployments is certainly harming Britain's forces, with divorces and suicides soaring and retention rates plummeting. But General Dannatt's unspoken sub-text was: you can fix this by pulling us out of Iraq.
There are already more British troops in Afghanistan than in Iraq, so the argument makes a kind of sense - concentrate your resources where they will make a difference. Except that Afghanistan, in the end, is also an unwinnable war, at least in the ambitious terms still used in the West.
Almost 30 years ago the Soviet Union, backing another modernising regime in Kabul against the deeply conservative prejudices of the countryside, committed an average of 200,000 troops into Afghanistan and kept them there for 10 years. And it still lost.
There have never been more than 50,000 Western troops in Afghanistan, and there is zero probability that the number might ever even double. Let alone that they might stay there for 10 years.
The war in Afghanistan is unwinnable, too, in the long run, and President Hamid Karzai's best chance of survival is for the Western troops to leave soon. Then he would at least be free to make deals with warlords, drug-dealers and renegade Taleban, in the traditional Afghan style. But if false hope about Afghanistan provides the pretext for pulling British troops out of Iraq, why not? When Mr Brown faces Parliament again in October, his biggest Iraq problem will not be pressure from the public. It will be pressure from the Army.
