Afghanistan: Afghanistan won't bow to U.S. 'pressure' over security pact: official --- (Reuters) - A senior aide to Afghan President Hamid Karzai accused the United States on Friday of trying to pressure elements of his government to accept a security deal that would shape the post-2014 U.S. military presence in the country. -- The bilateral security pact (BSA) was thrown into doubt last month when Karzai said he would sign only if new conditions were met, and even then only after April elections. -- If the pact is not signed Washington says it will consider a complete military withdrawal from Afghanistan, which remains embroiled in the insurgency of the Islamist militant Taliban. -- Failure to sign could also put Western aid running to billions of dollars in serious jeopardy, exposing the central Asian country's shaky economy to collapse. -- "If there is a perception in Washington that certain elements in Kabul can force President Karzai to succumb to any pressure, it is seriously flawed and mistaken." -- Faizi declined to elaborate on who these "elements" were. --- On Wednesday Karzai reacted angrily to a comment by Kerry at a NATO meeting in Brussels that the Afghan defense minister, Bismillah Khan Mohammadi, could sign the document instead of the president. -- "We cannot allow business as usual for the U.S. after the signing of the BSA," Faizi said. "It simply cannot be another ten-year chapter of raids on Afghan homes, civilian casualties and seeking peace in Afghanistan."
