Well, it is like the Biblical story about the Tower of Babylon - in the beginning, there was only one language and all the people in the world spoke it. However, because of many disputes and quarrels, they all separated and created numerous new languages. The same thing happened in the real world (if you don't believe in what the Bible says) - there used to be Proto-Indo-European language, but over time, it developed many new languages as people grew apart and created new nations.
The conflict over the establishment of the state of Israel.
Immediately after Israel declared itself an independent nation (free of British mandate control), a coalition of Arab states attacked, in 1948. Another war over the Suez Canal zone followed in 1956 -- though that was more a direct matter between Egypt and Israel (as well as Britain and France). Further wars between Israel and Arab neighboring states occurred in 1967 (the Six Day War) and in 1973 (the Ramadan or Yom Kippur War).
