( CNN ) -- Top Pakistani officials on Wednesday dismissed fears over the safety of the nation 's nuclear weapons revealed in U.S. diplomatic cables . `` Pakistan 's nuclear assets are safe , '' said Qamar Zaman Kaira , the information minister . `` All major countries , including the U.S. , have shown they 're satisfied with the security of our nuclear assets . '' U.S. diplomatic cables cited by The New York Times reveal concerns over Pakistan 's uranium stockpile , its role in the struggle against Islamic militants and its economic crisis . The documents are among the vast cache of U.S. State Department papers that WikiLeaks , a website known for leaking official secrets , began releasing Sunday to widespread condemnation from the United States and its allies . CNN can not independently verify the content of all the cables from the website . Cables revealed by The Times show that the U.S. ambassador in Islamabad was concerned over a supply of highly enriched uranium at an aging research reactor , allegedly enough to build several `` dirty bombs . '' The Times cites a cable dated May 27 , 2009 , in which Ambassador Anne Patterson said the Pakistani government was dragging its feet on an agreement that would allow the U.S. to remove the material . She said the Pakistani government was concerned that the `` sensational ' international and local media coverage of Pakistan 's nuclear weapons made it impossible to proceed at this time . '' A foreign ministry spokesman said fears over the nation 's nuclear weapons are misplaced . `` Their fears are misplaced and doubtless fall in the realm of condescension , '' spokesman Abdul Basit said . `` There has not been a single incident involving our fissile material which clearly reflects how strong our controls and mechanisms are . '' Basit said Pakistan has `` extended experience in handling nuclear stuff . '' Nuclear safety was not the only concern linked to Pakistan in the cables . One document cited says Pakistan President Asif Ali Zardari had told U.S. Vice President Joe Biden that the Pakistani military might `` take me out . '' However , Kaira said , the nation was not at risk of a coup . `` All of Pakistan 's institutions , including military , have learned lessons from the past , '' the minister said . `` There would be no military coup today . The people of Pakistan will not allow a coup . '' Other governments are also preoccupied by Pakistan , including Saudi Arabia , according to a CNN survey of the leaked cables . In a cable sent to Washington in February , Ambassador James Smith writes : `` King Abdullah firmly believes that Asif Zardari is the primary obstacle to the government 's ability to move unequivocally to end terrorist safe havens there ( 'when the head is rotten , it affects the whole body ' ) . '' Kaira refuted the accusation , saying the government is committed to the war against terrorism . `` We have won the war in many parts of the country and we are winning in other parts of the country . I admit the success is slow because the war is very long . '' A cable from June 2009 said Israeli Defense Minister Ehud Barak told U.S. diplomats that Pakistan was his `` private nightmare , '' suggesting that the world might wake up one morning `` with everything changed '' after a potential Islamic extremist takeover . CNN 's Reza Sayah and Tim Lister contributed to this report .
