WHITE HOUSE SPOKESMAN ROBERT GIBBS on Monday expressed fresh concerns over rare comments from Afghan President Hamid Karzai. The president criticized the United States and its Western allies of engaging in fraud in last year’s presidential vote as part of efforts to deny him a second term. Gibbs told reporters, "The remarks are genuinely troubling. The substance of the remarks, as have been looked into by many, are obviously not true." Elsewhere, Karzai, in an interview with the BBC, stood behind accusations that the West was responsible for election fraud in Afghanistan, saying, "What I said about the election was all true, I won't repeat it, but it was all true." Trading barbs with U.S. President Barack Obama's administration — twice in four days — is not the only thing Karzai has done. In a closed-door meeting with a select group of Afghan lawmakers, Karzai reportedly threatened to join the Taliban insurgency if he was continuously pressured by the West to engage in reforms. Lawmaker Farooq Marenai, who represents the northeastern province of Nangarhar, told AP that Karzai said that "if I come under foreign pressure, I might join the Taliban." Marenai added that Karzai remarked that the Taliban would then be redefined as a resistance movement fighting foreign occupation instead of being perceived as rebels trying to topple an elected government. The United States has never been interested in getting rid of Karzai for the simple fact that a replacement would be hard to find. Karzai's spokesman has officially denied that the Afghan leader threatened to align with the jihadist movement. Whether or not Karzai made the statement is less important than the fact that relations between Karzai and Washington have seriously deteriorated. It is not clear that the United States has decided to withdraw its support from him as Gibbs told reporters Monday that a May 12 meeting between Obama and Karzai at the White House was still being held as scheduled. Despite the badly damaged relationship, Karzai cannot easily be replaced. He became president as part of a compromise after the fall of the Taliban regime because Taliban fighters assassinated Abdul Haq — Washington's first choice — in October 2001. Since then he has managed all the various regional warlords and factions (save the Taliban, of course) to the extent to which he has held the country together. That the Karzai regime is corrupt is nothing new. It has been for the past eight years. But the United States has never been interested in getting rid of Karzai for the simple fact that a replacement would be hard to find. During his tenure, Karzai has been built up so much that even good possible replacements do not exist, at least ones capable of dealing effectively with the Taliban. At this point it is not clear that Washington wants or is able to get rid of the only leader Afghanistan has known in the post Taliban period. Karzai also has strong incentives to appear tough in public and distance himself from the Americans — especially to attempt to dispel accusations that he is merely a puppet. Some of this could well be manufactured as Karzai attempts to consolidate power following contentious elections. The important question is: How deep do these tensions run? As there is no shortage of Karzai critics in Washington, it is important to realize that the extent to which the tensions are real is symptomatic of deeper functional rifts. Karzai is as much a political reality in Afghanistan as the Taliban, and he has only just now begun a second five-year term. Rifts aside, Karzai is an inescapable player in this extremely pivotal year in Afghanistan.
