In sum, it notes that there is no reasonable alternative to the general direction that Bush is taking.
Urging the reading of the whole piece, we tantalize with a quotation:
In reality, there is no credible alternative. The Iraq Study Group proved rather better at setting out the many problems that exist in Iraq than in offering precise solutions. Its recommendation that the White House co-opt Iran and Syria as its allies in Iraq does not look remotely plausible. The idea that suddenly withdrawing American soldiers from the country would convince Shia and Sunni hardliners to be more charitable to one another is equally improbable. Mr Bush’s domestic foes, notably Nancy Pelosi, the new Democratic Speaker of the House of Representatives (who has a minimal record in foreign policy) and the increasingly surreal Edward Kennedy, would simply abandon Iraq and be done with it.
