There are differences between the USA and Israel.
In the USA all people are created equal, and we all have equal rights, and we do not need walls because our neighbors are Christians just like we are.
In Israel, the Jews are God's chosen people, and the Palestinians are their enemies because they are Muslims and they are taught to hate Christians and to hate Jews, and then you have the other Muslim nations who are using the Palestinians as a weapon against the Jews. Saddam and Arafat were horrible, may they burn in hell. And the Jews need walls to keep their enemies out. The Jews used to have suicide bombers blowing themselves up at bus stops as directed by Arafat, and then Saddam would give money to the families of the suicide bombers. All men are not equal in the Middle East, and your neighbors are your enemies.
So, the world is different in different areas, and people need to remember to view each place by the specific circumstances of each place.
Salute,
