World Conflicts
The most current problem the world involves North Korea. Imagine a country that openly hates the United States, already posses the material to make a nuclear weapon. Now imagine that the same country already successfully tested a nucleur bomb. North Korea has achieved this and with this hopes to join the club. Basically the a club that only countries with nuclear weapons can join. Almost every nation, uncling one of North Korea's biggest ally China has frowned at the actions of North Korea, hoping to stop them at their testing in its tracks.
In a way nuclear bombs prevents nations from going down the path of World War III. Countries are afraid to engage in full combat with other countries that pocess weapons of mass destruction. Nuclear weapons act as invisible shields that prevent wars among Super Nations. It is normal to fear a country that has nuclear weapons especially if it is a country with a small source of economy. North Korea is a country that does not have enough resources to take care of its people, so how would it take care of its nuclear weapons. A country that has little money, has a bigger potential of selling its nuclear weapons to other countries that might hate the U.S.That is why alot of nations fear North Koreas plans for nuclear weapons We should not fear the future though because it would be a mistake to use nuclear weapons on the United States. It would be a mistake because the U.S has one of the largest arsenal of nuclear weapons.
What we need to do is find other ways of preventing the use of nuclear weapons, but that may have it own set of problems. If nuclear weapons were to become obsolete, the invisible shield that prevents a large scale wars would go down. The world is full a conflict new and more dangerous weapons will be created and hopefully future generations will find ways to make lasting peace.
