Is there any possible counter measures for a launched nuclear warhead?
No inter continental missiles are so fast and many have warheads that split to attack multi targets.Trident which is launched by submarines travels at 13000 mph so fast that it causes an half inch gap between it and the water it carries an explosive load equivalent to every bomb used in war since warfare began including WWII atom bombs there is no known way of intercepting such a missile.Interception has been described as trying to shoot a bullet with another bullet.
