NATO in Afghanistan will remain on the offensive against Taliban forces regardless of the expected surge in attacks by the insurgents in the spring, NATO Secretary General Jaap de Hoop Scheffer said on Wednesday. “NATO has not the slightest intention to cede the initiative to anyone - spring, or no spring.” He said the alliance was seeking closer cooperation with Pakistan to check infiltration. He rejected a Pakistani suggestion to mine and fence Afghan border. NATO spokesman Mark Laity also said in Kabul the force had “strong reservations” about Pakistan’s plan to fence its border with Afghanistan.
