Former American Ambassador to the United Nations John Bolton said the Bush administration's continued support to President Pervez Musharraf is necessary to prevent nuclear weapons from falling into the hands of terrorists and fundamentalists.He blamed the present American government for ‘contributing to the instability in Pakistan by not strongly supporting Musharraf’.Promoting his new book, Surrender Is Not An Option, Bolton wanted the US to focus less on election and more on ensuring that al-Qaeda terrorists do not lay hands on nuclear weapons.Expressing doubt that a civilian government in Pakistan could keep military under control or nuclear weapons out of the reach of terrorists and fundamentalists, Bolton said he was not defending Musharraf."But I am here to say that an appreciation of Pakistani history doesn't give much reason for confidence that a civilian leader can keep the military under control and keep the nuclear weapons secure," he said.Bolton resigned as the US Ambassador to United Nations following stiff opposition from the members in Senate which was unlikely to confirm him to the post. He now works at a Washington-based conservative think tank, American Enterprise Institute.Bolton said the highest strategic interest of the United States should be to ensure that weapons of mass destruction remain secure. He wants the United States to learn from the experience of enforcing elections in Palestinian territories that resulted in the victory of Hamas.
