LONDON - Britain has offered its full backing to a renewed military offensive inside Pakistan, as UK ministers confirmed the country was now "part of a single campaign" alongside Afghanistan. Defence Secretary John Hutton said the UK supported targeting Pakistan-based Taliban and Al-Qaeda positions and urged Europe to assist in eradicating insurgents in the tribal region bordering Afghanistan. He said the time has come to target Taliban and Al-Qaeda havens inside Pakistan, adding the military objectives in the region must now have "an equal focus on both countries". He said, "Al-Qaeda is in retreat, scuttling across the border into Pakistan, trying to buy time and desperate to regroup. But there must be no let-up, no hiding place for it." He indicated that Britain must play a principal role in supporting the American military effort in the region. "In Europe, we can no longer offload the tough questions about how we deal effectively with Al-Qaeda and the Taliban in Pakistan," he said. "The political burden of dealing with the Pakistani side of the border must be shared. And there are many European countries with strong ties to Pakistan that can more effectively share that burden with America," he added. British Ministry of Defence spokesman said that London was ready to offer military, political and diplomatic support to a renewed offensive in Pakistan's tribal lands, but what precisely that entailed was dependent on the resources other NATO members were prepared to offer. However, the initial aim would be to support the Pakistani government, rather than place British forces on the ground inside the country. Last week British PM Gordon Brown termed Al-Qaeda in Pakistan as the greatest threat to the UK national security strategy. Two thirds of terror plots uncovered by British intelligence agencies have a Pakistani connection. Additional military resources are also likely to be deployed to the region once Britain withdraws its 4,000-strong force from Iraq this July, with moves to increase troop numbers in Afghanistan from 8,300 to potentially above 10,000 within a year. The new-found focus on Pakistan will dominate NATO's 60th anniversary summit in Strasbourg this week, in which Britain and the US will attempt to drum up more support for the AfPak mission. President Obama has promised 21,000 more troops for Afghanistan. By contrast, NATO has sent 32,000, with Germany so far sending just 3,640, France 2,780 and Spain 780. These three countries will be under pressure to increase their contingent, sources said. Meanwhile, UK Defence Secretary, Hutton, has condemned "the massive leadership imbalance" between Europe and the US in NATO. He said it was an imbalance set to grow in the coming months as America committed vastly more resources of every kind to the mission in Afghanistan."
