US special representative for Pakistan and Afghanistan Richard Holbrooke has said that Al-Qaeda, the world's foremost terror outfit, is under tremendous pressure in the Af-Pak border region with half of its top 20 commanders eliminated. <br/> Holbrooke said in an interview to CNN that their excessive brutality, the backlash against things, like the bombing of the wedding in Jordan, the beheading of people, the videotape in Swat of the flogging of the young girl, has created a revulsion against them.<br/>Attributing the success against Al Qaeda and Pakistani Taliban to increased communications between Washington and Islamabad, he cited the arrest of Taliban's No 2 as evidence of Pakistan's evolution from the country on the verge of collapse to a more stable political system now.<br/>
