Even with the deep cuts the START follow-on treaty requires in U.S. strategic nuclear delivery vehicles, it may still be possible to retain a nuclear "Triad" of long-range bombers and land- and sea-launched ballistic missiles.
Such reductions would likely preclude the maintenance of the sort of balanced deterrent posture based on a "Triad" of land- and sea-based missiles and long-range bombers that the United States has correctly deemed necessary for decades - and that may be needed more than ever in the future.
