The US is keeping a close tab on efforts by Pakistan to keep its nuclear arsenal safe from militants, but feels that the recent terrorist attacks in the country does not pose a threat to the atomic weapons.
Noting that the Obama Administration is concerned about the safety of Pakistan's nuclear weapons and nuclear proliferation through the A Q Khan network, Secretary of State Hillary Clinton said these are part of every engagement that the US has with Pakistan.
"We have been reassured about the security of the nuclear-weapons stockpiles and facilities," she said in an address on non-proliferation to the US Institute of Peace.
"But we have certainly... made our views known and asked a lot of questions and are supporting the Pakistani government in their courageous efforts against these extremists," Clinton said.
Reiterating strong US concerns on the threats of nuclear proliferation, Clinton said "it is obviously a matter for which we are watching very closely."
On the threats posed by the resurgent Taliban and al-Qaeda to Pakistani nuclear facilities, the Secretary of State said, "we don't think that those attacks pose a threat to the nuclear command and control or access."
