2. Today there is a civil war in Yemen, with the Saudis supporting the Yemen
government and the Iranians supporting the Houthi rebels. In the period
1962-1970 there was again civil war in Yemen, but this time the Saudis were
supporting the King of Yemen and the Egyptians of Gammal Nasser were
supporting his opponents. Great Britain was supporting the Saudis, and the
Soviet Union was supporting the Egyptians. Poor Yemen is of great strategic
value for the control of the Red Sea, and for attacking Saudi Arabia if you
are Egypt in the 60s or Iran in the 2015.
