( CNN ) -- Pakistani President Asif Ali Zardari on Tuesday insisted that his country 's nuclear arsenal is `` definitely safe , '' despite growing concerns about recent gains by the Taliban along the country 's border with Afghanistan . Pakistani President Asif Ali Zardari insists his country 's nuclear arsenal is `` definitely safe '' from militants . In an interview with CNN 's Wolf Blitzer , Zardari responded to the fact that the United States does n't know the locations of all of Pakistan 's nuclear sites . He also addressed the Obama administrations concern over whether the weapons are vulnerable to Taliban fighters who are gaining control of some border regions . `` They ca n't take over , '' Zardari said , referring to militants . `` We have a 700,000 ( person ) army -- how could they take over ? '' For the last two weeks , Pakistani troops have been battling Taliban fighters in Buner and Lower Dir , two districts bordering the Swat Valley -- a broad Taliban stronghold in Pakistan . Army generals claim to have killed scores of militants . Pakistan 's government recently signed a deal that would allow Islamic law , or sharia , in the Swat Valley , in exchange for an end to fighting . Still , Pakistan 's military is continuing an assault on militants in Taliban-held areas after they seized territory in violation of the agreement signed by Zardari . Last week , U.S. President Barack Obama said Pakistan 's government appears to be `` very fragile '' and argued that the United States has `` huge national security interests in making sure that Pakistan is stable '' and does n't end up a `` nuclear-armed militant state . '' And , after making two visits to Pakistan in the last three weeks , Adm. Michael Mullen , chairman of the U.S. Joint Chiefs of Staff , indicated Monday that he is `` gravely concerned '' about recent Taliban and al Qaeda gains across much of southern Afghanistan and in Pakistan . Pakistan 's nuclear weapons are `` definitely safe , '' Zardari said Tuesday . `` First of all , they are in safe hands . There is a command and control system under the president of Pakistan . And Buner ... there has been fighting there before . There will be fighting there again and there will always be an issue of people in those mountains that we 've been taking on . '' Zardari 's comments came as the Obama administration prepared for meetings set for Wednesday with Zardari and Afghanistan President Hamid Karzai to discuss security in the region . A senior administration official told reporters that the U.S. objective of the meetings is `` an alliance with these countries against a shared threat . '' Watch Pakistan 's U.S. ambassador discuss the Taliban insurgency » . Zardari and Karzai will also be visiting key congressional leaders and policymakers in advance of meetings with Obama and Secretary of State Hillary Clinton . A bill called the Enhanced Partnership with Pakistan Act of 2009 , introduced by Sens . John Kerry , D-Massachusetts , and Dick Lugar , R-Indiana , would authorize $ 7.5 billion in non-military aid to Pakistan over the next five years to foster economic growth and development , and another $ 7.5 billion for the following five years . Zardari , for his part , said he is grateful for the financial aid Pakistan has received from the United States , but said he needs `` more support . '' `` I need drones to be part of my arsenal . I need that facility . I need that equipment . I need that to be my police arrangement , '' he said . The U.S. military has carried out airstrikes against militant targets in Pakistan , after Zardari 's government was criticized for not cracking down on militants along the Afghan border . The unmanned drone attacks have rankled relations between Pakistan and Washington . Asked whether the U.S. strategy bothered him , Zardari said , `` Let 's agree to disagree . ... We 're still in dialogue . '' Zardari also denied speculation by some Congressional lawmakers that his country has used most of the $ 10 billion given by the United States to strengthen its arsenal against a threat from nuclear rival India -- as opposed to going after the ongoing militant threat . `` They 've given $ 10 billion in 10 years , a billion nearly a year for the war effort in -- against the Taliban , and the war that is going on , '' he said . Zardari also addressed his government 's apparent resistance to significant U.S. involvement on Pakistani soil . Recently , U.S. Defense Secretary Robert Gates observed , `` There has been a reluctance on their part up to now . They do n't like the idea of a significant American military footprint inside Pakistan . I understand that . And -- but we are willing to do pretty much whatever we can to help the Pakistanis in this situation . '' Zardari called Pakistan 's relationship `` pretty strong '' and said , `` We are asking . We 've been asking for a lot of help , and it has been in the pipeline for a long time . ''
