Yes, intercontinental ballistic missiles should be banned because of the severity of damage they can cause. They also permit countries to attack other countries that are so far away they don't have the ability to fight back and defend themselves against such an attack. Many countries couldn't be trusted with this type of weaponry.
I think that intercontinental ballistic missiles should be abolished from all over the world. I think they are a danger to the world and society. Too many rogue nations operate them without regulations as well. I think that the nations of the world should get rid of all of them.
Intercontinental ballistic missiles should not be abolished. Unfortunately there are different countries in the world who are not allies and can be considered hostile enemies. Since many of these countries have intercontinental ballistic missiles, it is necessary to possess intercontinental ballistic missiles for purposes of defense. In order to deter a potential attack from an intercontinental country America must posses intercontinental ballistic missiles to intimidate their opponents.
ICBM's have been developed and perfected for defensive and offensive warmking purposes, but it seems like people have gone too far to reverse the trend of ICBMs. They are a popular mainstay in both American and Russian weapons caches, and they each have so many that to abolish them would be difficult.
It makes little sense to destroy all ICBMs and all the technology that goes into the creation of ICBMs. ICBMs might not be needed today, especially now after the end of the Cold War, the far lower threat of nuclear war, and the invention of nuclear subs carrying warheads, but, still, it seems foolish to abolish the ability to create something.
