aleaf,
You said “The united states owns the strongest arms in the world and can destory other countries once he decides to do.” I don’t think that they would be able to destroy a country if they like. My country have this arm too but i don’t agree with it. North korea wants the nuclear werapon ? But would they want it if no one else country had it? The fact that we can decide which country are supposed to have it makes countries which don’t have it inferior. And it may be the reason for whixh they want the arm. If they didn’t feel danger from other countries they wouldn’t want to have it. My point of view is that no country should have something which could be able to destroy another country.
