It's called Propaganda. The Israelis have learned well from the German Nazi Regime, the USSR and South African Apartheid.
Israelis combined all the knowledge they got from these 3 racist systems and perfected their own Propaganda machine so that they can always be portrayed as "the poor victims who only commit genocide because they were attacked first."
And do you want to know an interesting thing? The Americans are their main supporters but that would change if the truth about the death of JFK and the 9/11 attacks were told because in both cases, all the evidence points to the Zionist Murder Machine.
