LAHORE Marred by mistrust and Washingtons assertiveness, fractured US-Pakistan diplomatic relations have reached on the brink of collapse as both the states, otherwise ally in war on terror, are hardly maintaining ambassador-to-ambassador-level diplomacy with no high-level contacts or exchanges for the several weeks. Despite significant developments with reference to Washington-Islamabad relations, which took place in the recent past from abduction of Dr Warren Weinstein to the arrest of Younis al-Mauritani and the 10th anniversary of 9/11 attacks there was no contact between the top leadership of both the countries. Well-informed sources confirmed to this reporter that neither the top military leadership nor the big guns in democratic governments held any direct meeting or telephonic conversation for the last several weeks. No top leader from both sides visited the other side. And to my knowledge, we dont have any information regarding the expected or possible high-level meeting between the top leadership of the both the sates in near future, a senior federal government official said on Thursday. During background discussion over the Pak-US diplomatic scenario, American and Pakistani officials agreed that the deadlock was yet to break as both sides lack commitment to repair the fractured relations. Unlike Raymond Davis case, the US top authorities did not contact Pakistani leadership following the US development expert Dr Warrens abduction from Model Town on August 13. Last week, Pak Army announced that the Inter-Services Intelligence (ISI) and Frontier Corps arrested Younis al-Mauritani, blamed for planning and executing international operations for al-Qaeda. Al-Mauritani was nabbed along with two other senior operatives of al-Qaeda Abdul Ghaffar al-Shami (Bachar Chama) and Messara al-Shami (Mujahid Amino). The US top leadership is yet to contact their counterparts in Islamabad for joint investigations, sources added. Similarly, on the 10th Anniversary of 9/11 attacks, both the states preferred to keep silent and no direct contact was seen at the heist level. The flare-up in tensions came after the US special forces killed al-Qaeda Chief bin Laden in a unilateral action in Abbotabad on May 2 this year. The Obama administration has adopted an increasingly hostile stance towards Islamabad in the aftermath of its Operation Geronimo by launching massive propaganda campaign against the nuclear-armed Islamic state, particularly its security forces and the ISI. A Pentagon official on Wednesday claimed that al-Qaeda leader Ayman al-Zawahiri was still hiding in Pakistan, days after the release of a video entitled 'The Dawn of Imminent Victory in which he said he was praying this years Arab Spring would be followed by a gloomy, bitter-cold American winter. A senior official in the foreign ministry straightforwardly rejected the US claim that al-Zawahiri was hiding in Pakistan and termed the accusation as part of the US propaganda campaign. This is a dangerous trend leading to psychological grumble and mental fissures between the coalition partners. US policy makers must understand that cooperation for a cause cannot be sought through coercive policies and negative schemes, the official said druing a brief chat with this scribe. After repeated attempts, an American official, on the condition of anonmity, agreed to speak on the issue but breifly. In the backdrop of present scenerio, the official said, the brazen attack on the US Embassy and Nato headquartes in Kabul had frustrated the Obama administration. Pakistan is unwilling to take decisive action against militant groups such as the Haqqani guerrillas in North Waziristan. The situation could worsen in the days to come, the American added. The official went on saying: Relations with Islamabad are difficult because elements of government have links with Haqqani network, the Qaeda off-shoot staging attacks on US-led troops in Afghanistan. A day earlier, US Defense Secretary Leon Panetta vowed action inside Pakistan to stop a militant group, which according to his version is staging attacks against the US-led Nato forces in Afghanistan. If any foreign force tries to conduct a misadventure, Pakistans armed forces will react very strongly with all their resources, an intelligence official said without mentioning Panettas statement. After 9the /11, the USA unleashed a 'shock and awe crusade against Taliban to defeat them quickly but failed to achieve her objectives as Taliban proved more resilient than what was expected by the US planners. Today, the US defeat in the hands of rag-tag Afghan Taliban is a stark truth; no matter how grave is the embarrassment for the worlds sole superpower. Russia and China would not like the US to hang-on in Afghanistan any longer. The sooner they leave, the better it would be for peace to prevail in the region. Analysts say the Pak-US relations should be based on a long-term strategy and the sacrifices rendered by Pakistan should be acknowledged by the American authorities.
