If nuclear weapons were still on this planet I think in about 200 years the human race will be wiped out. The also let out high levels of radiation which can cause cancer which leads to death. In my opinion I think nuclear weapons should be abolished. That's my opinion
Although nuclear weapons are extremely dangerous, multiple countries have there own and so they wouldn't fire at a country that has one, scared of whether they would be attacked or not.
Also, they haven't used them in a war since the attack on Hiroshima and Nagasaki, therefore they only use them as a threat
