The big problem with Palestine in the Muslim Terrorist Organization known as Hamas.
I recommend that you read about Haj Amin al Husseini in the book "Icon of Evil, Hitler's Mufti and the Rise of Radical Islam"
Haj Amin al Husseini was The Grand Mufti of Jerusalem in the 1920s and 1930s.
In the 1930s Haj Amin al Husseini formed an alliance with Adolf Hitler and the NAZIS to kill all of the Jewish People in The MIddle East.
During World War II, Haj Amin al Husseini was a guest of Adolf Hitler and the NAZIS in Germany.
Haj Amin al Husseini was put in charge of a Waffen SS Unit.
Under the leadership of Haj Amin al Husseini that Waffen SS unit killed all of the Jewish People in Bosnia.
After World War II, Haj Amin al Husseini returned to The MIddle East and started numerous schools (Madrassahs) designed to trin Muslim Boys to be Muslim Terrorists and kill all of the Jewish People in The Middle East.
Some of those boys in Haj Amin al Husseinis schools (Madrassahs) went on to found Muslim Terrorist Organizations of their own.
Those Muslim Terrorist Organizations founded by Haj Amin al Husseini's students include but are not limited to Hamas, Hezbollah, Islamic Jihad and Al Qaida.
Hamas is the organization that has been firing rockets at Israel from Gaza.
Essentially all of these Muslim Terrorist Organizations espouse a form of radical Islam created by Haj Amin al Husseini, which is a mixture of Islam and NAZISM.
All of these Muslim Terrorist Organizations are dedicated to fulfilling the goal of Haj Amin al Husseini and the NAZIS of killing all of the Jewish People in The Middle East and the rest of the world.
With respect to the Zoo Animals, The Israelis did not kill any Zoo animals. That is a false story that was put out by The Hamas Propaganda Machine.
