Few things have exemplified or strained the tenuous relationship between the US and Pakistan more than what happened here earlier this year in a Bada Bada Pakistan, the US commando raid that killed Osama bin Laden. It raised questions in the US about Pakistan's friendship and angered many Pakistanis, upset by America's unilateral action. But Cameron Munter, the US ambassador to Pakistan, told VOA the two nations must remain united against a common enemy. The problem we have here is that they are dealing with ruthless people who are bringing something to Pakistan that Pakistan didn't want. Just like America didn't want an attack on 9-11, Pakistan doesn't want these kinds of terrorists. They are bringing them here and trying to drive a support, trying to make this sound as if it is somehow a fight that we shouldn't be in together. When the United States launched its military campaign in Afghanistan, it inserted itself into a far larger, far messier, regional struggle. The tensions between India and Pakistan dominate the subcontinent. They have fought four wars and countless skirmishes since their creation more than 60 years ago. Both possess nuclear weapons. Pakistan's western border with Afghanistan is porous, nearly impossible to control. Ethnic push-tunes live on both sides of disputed line, arbitrarily drawn by a 19th century British statesman. Only hello to the former Pakistani ambassador to the US says Washington didn't fully understand the ramifications of sending troops to Afghanistan. Well I think the blowback of 10 years of war in Afghanistan has been devastating for Pakistan. It led not just to the prolongation of a war that destabilized the region, but it also led to the defeat of America's own objectives. Because America was unable to distinguish and therefore separate Al Qaeda from the Taliban. Pakistan feels that this war in the manner it was fought was pushed into Pakistan's border regions. Taliban, Al Qaeda and other insurgents fled into Pakistan when the US-led coalition arrived in 2001. And after Pakistan sided with the US, many of the fighters in those tribal regions decided Pakistan's military and government were legitimate targets. That led Pakistan's military to pursue some insurgents, but not others, notably the Hakanim Network allied to both the Taliban and Al Qaeda. The US responded with drone attacks on insurgents inside Pakistan, sparking a wave of anti-Americanism. Many Pakistanis feel the US is violating their nation's sovereignty. When Ambassador Munter says for the last 10 years the two nations have stood together and suffered together. And he says with that shared experience, they should hold together. Both countries have shown resilience, I think. I think it's a good sign for our relationship. Both countries have suffered and we honor the sacrifices people have made. But huge challenges remain and we're going to have to stay together in order to face them. Parties on both sides of the relationship question that though. Whether it's in the American Congress where there's talk of cutting aid or in Pakistan where there's anger and talk of breaking with America. For now, the two remain allies.
