Yesterday I mentioned that India had successfully test-launched an undersea missile. Today the head of Pakistan’s navy declared that the test would trigger a regional arms-race. (There are some doubts as to whether China has already mastered the technology.): “We are aware of these developments, and these developments are taking place with a view to put nuclear weapons at sea and it is a very, very serious issue,” the state news agency quoted him as saying. Of course, having tested three nuclear capable missiles in the past year, Pakistan is hardly in the position of pointing the finger.
