WASHINGTON (Online) - For years, US officials have pushed Pakistans military to attack the Haqqani network, or at least block its ability to cross the Afghan border, or at least cut off whatever financial and other support Pakistans spy service continues to provide to the insurgent group, reported The Washington Post. All to little avail. But it turns out that US officials have at times also tried another, more humble approach: simply asking Pakistani leaders to appeal to Haqqani to refrain from certain attacks. Earlier, this month, Gen. John Allen, the US commander in Afghanistan, travelled to Rawalpindi to share intelligence with COAS Gen.Ashfaq Parvez Kayani. The intelligence indicated that the Haqqanis were planning a truck bomb attack on a US military installation in Afghanistan. A US military official familiar with the Sept. 8 visit, which was first reported by The Guardian, said Allen asked Kayani to intervene not by disrupting the plot but by using his influence to dissuade Haqqani forces from carrying it out. 'We knew [an attack] was coming but we didnt know where, a US military official said. 'We didnt know when, what trucks, the Post said. Three days later, on Sept. 11, a truck bomb killed two Afghan civilians and wounded nearly 80 NATO soldiers at a military base in the Wardak province. The official said the US military had drawn 'no conclusions as to whether Kayani had tried to intervene. But Adm. Mike Mullen, Chairman of the Join Chiefs of Staff, told a Congressional panel that the Haqqani network was a 'veritable arm of the Pakistani intelligence servicean assertion that other top US officials involved in the region are calling provocative and overstated. The Sept. 8 meeting and request suggests a US idea to two realities: the Pakistan-Haqqani relationship may never be severed, and CIA drone strikes and US military raids arent enough to stop Haqqani attacks in Afghanistan.
