Furthermore in South Asia with the development of nuclear technology and an arsenal of nuclear weapons the Southeast Asia neighbors of Pakistan and India continue to be a source of worry for the world community as they could be a flashpoint for a nuclear war that could eventually engulf all their neighbors and lead to consequences that might even lead to World War III.
Following the 9/11 attacks, Pakistan authorities had to decisively align themselves with the United States against the war with terrorist forces by providing strategic and logistic support and prior to the invasion of Afghanistan by Russia and the consequent war, which eventually forced the Russians to
