第四次世界大戰

Well, I don't agree with this so much,
Nowadays, So many countries(For example China, America, United Kingdom...but not developed coutries) agreed that the world should go to be peaceful and no more war again. In globalization, so many courtries joined many world organizations, such as WHO(World Hygiene Organization), WTO( World Trade Organization)...they all have signed the agreement and try to be friend with the other countries, they also help each other. Because of globalization, someone said that the world will go to be in one in the future, there maybe a world president in the future too. So, there won't be a war again, because the world have already in one. The percentage of occur the war is small.
If there really is a third war, I think the countries may use the atom bombs, that may cause so many people to die. However we must remember that, The population of the world is still increasing. Maybe the bombs and weapons really will kill so many people, but they won't kill all of them. The civilization will be still here. Also the technology is wonderful. It will protect the people and the society, even a country.
If the third war reallyl come into the future, then, germs or viruses will be used to be a weapon.
Then, now talking about the fourth world war. Because the weapons are not enough to disturb the human's civilization, so the using of weapons of the fourth world war, I think because of the war , the technology will come along, the weapons will be high technolgy. So, I expect that the weapons of the fourth war maybe robots or the laser weapons( such as laser gun).
Anyway , I really hope that there are no more war in the world, why don't we live in peaceful?

I agree

As the weapon of most of the country is very strong, only a atomic bomb can destory the civilization of the world when there is the third World War.
All people will start to live in the Stone Age
therefore when there is the forth World War, all people will using stone to take the war
