ISLAMABAD In a bid to get Raymond Davis off the hook, the US government and establishment might threaten the top Pakistani govt functionaries of freezing their foreign accounts if the US undercover agent was not set free. Credible diplomatic sources see the sudden silence of the US authorities regarding Davis issue as 'silence before the storm. According to the Deputy Head of Mission of a European state, a new spate of pressure tactics coming from the US government and military would surface in the days ahead. According to him, the US Congressmen, military officials and govt functionaries are expected to visit Pakistan to convey the hostile messages of the White House that foreign assets and bank accounts of top Pakistani govt functionaries be frozen and pending cases against them be revived in case Raymond was not set free. 'Based on my knowledge and experience of diplomacy, I can safely say that this is 'silence before the storm. If John Kerry is to visit Pakistan again, which Im sure he definitely will, his tone and tenor would be different altogether. This time he wont be a soft spoken Congressman anymore but a blunt envoy who would convey the hostile messages of his top bosses regarding release of Raymond Davis, the diplomat said during an informal meeting with this scribe on Wednesday. 'Pakistani politicians at the helm of affairs perhaps would be told to face the music in the form of revival of their cases abroad, he added. The diplomat said that as per his information, new US Special Envoy for Pakistan and Afghanistan, Marc Grossman, Admiral Mike Mullen, Chairman Joint Chiefs of Staff, US Secretary of State Hillary Clinton and Senator John Kerry were likely to come to Pakistan for this purpose. Talking to The Nation, Lt Gen (Retd) Hameed Gul termed the reports as true that US might threaten top Pakistani government functionaries of freezing their foreign assets. Asked if there were any chances of any such happening, the former ISI chief said, 'Of course this might happen. The US had facilitated the NRO deal with blue-eyed politicians on the condition that these politicians would keep supporting US on each and every issue. According to Hameed Gul, when President Asif Ali Zardari was charged for corruption cases and his foreign accounts came under scrutiny, the US President Barack Obama was heading the US Senates Committee dealing with the issue and Obama was instrumental in brokering the notorious National Reconciliation Ordinance (NRO). 'The NRO deal was all about concealing the notorious secrets of Pakistani politicians, who, in return, submitted their loyalties to US, he said. 'Now the US would use NRO as blackmailing tool to save the skin of the CIA agent, Raymond Davis, he added. To a query, he said that US had adopted silence over Raymond Davis issue because the international media had started exposing the activities and motives of Raymond Davis in Pakistan. 'Now that their own newspapers have starting printing the stories exposing the covert and notorious activities of the US agent, the US has turned silent but it would keep pressurising Pakistan by hook or by crook, he said. He said Pakistans nuclear assets were in safe hands but the US undercover spies were making efforts to acquire information about Pakistans sensitive defence installations. 'These spies would never succeed, he stated. Hameed Gul said the restlessness that Davis detention had created in US camp shows that he knows a bit too much. 'In order to US pressure, the loyal and patriotic politicians need to step ahead and take a stand. Nawaz Sharif has talked about revolution, he should play his part in this regard, he suggested.
