World War 3 doesn't seem long because if you notice the war between UK and Russia is going on and on the other hand there is a war going on between Palestine and Israel.  You all know and you have seen that Iran launched many rocket attacks on Israel on behalf of Palestine to destroy Israel from the middle.  If any other country participates in Israel's life, there will be a big situation of World War III and if America goes to Israel's side and attacks Iran or Palestine.  Then the upper leg will attack and join another country in what is most likely a World War 2. We all pray that it doesn't happen.  When World War III starts, people will die of hunger and the economy The world economy will be in a very bad state and people will die of lack of food and it's very, very sad.
