WASHINGTON - A new opinion poll has indicated that roughly three in four Pakistanis (74percent) view the United States as an enemy, and offer bleak assessments of PaK-US relations.The survey, released by the US-based Pew Research Centre on Wednesday, also shows that President Obama is held in exceedingly low regard. Indeed, among the 15 nations surveyed in both 2008 and 2012 by the Pew Global Attitudes Project, Pakistan is the only country where ratings for Obama are no better than the ratings President George W Bush received during his final year in office, according to the study. Only 13 percent of Pakistanis think relations with the US have improved in recent years, down 16 percentage points from 2011, the poll says. Strengthening the bilateral relationship is also becoming less of a priority for Pakistanis. While 45percent still say it is important to improve relations with the US, this is down from 60 percent last year.Moreover, roughly four out of 10 believe that American economic and military aid was actually having a negative impact on their country while only about one out of 10 think the impact was positive. Additionally, over the last few years, Pakistanis have become less willing to work with the US on efforts to combat extremist groups. While 50 percent still want the US to provide financial and humanitarian aid to areas where extremists operate, this is down from 72 percent in 2009. Similarly, fewer Pakistanis now want intelligence and logistical support from the US than they did three years ago. And only 17 percent back American drone strikes, even if they are conducted in conjunction with the Pakistani government.Since 2009, the Pakistani public has also become less willing to use its own military to combat extremist groups, the study says. Three years ago, 53 percent favoured using the army to fight extremists in the FATA and neighbouring Khyber Pakhtunkhwa, but today just 32 percent hold this view. Overall, concerns about extremism have ebbed since 2009, when the Pakistan military was battling Taliban-affiliated groups in Swat. Then, fully 69 percent were concerned that extremists might take control of Pakistan, compared with 52 percent today. While concerns about extremism may have decreased, extremist organisations remain largely unpopular, it said. Majorities, for example, express a negative opinion of both Al-Qaeda and the Taliban, as has been the case since 2009. In 2008 – before the peak of the Swat conflict – pluralities expressed no opinion about these organisations. When Pakistanis are asked more specifically about the Afghan Taliban and Tehrik-i-Taliban, opinions are again, on balance, negative, as they were in both 2010 and 2011.Views are somewhat more mixed, however, regarding Lashkar-e-Taiba. Roughly 1 out of five Pakistanis (22 percent) have a favourable view of Lashkar-e-Taiba, while 37 percent give it a negative rating and 41 percent offer no opinion. Meanwhile, a solid majority (64 percent) offers no opinion about the Haqqani network. Respondents in the Khyber Pakhtunkhwa consistently express more negative views about extremist groups than those in other provinces. The Pew Research Centre said face-to-face interviews were conducted with 1,206 respondents between March 28 and April 13. The sample covers approximately 82 percent of the Pakistani population. The poll in Pakistan is part of the larger 21-nation spring 2012 Pew Global Attitudes survey.
