A rise in tensions
Gaza received many of them after the forced removal, which explains its high population density today. From then on, Israel would continue to enforce its ethnostate with The Law of Return in 1950. The law stated that every Jew is an Israeli citizen by right, and would be assisted in settling in Israel. The Absentee Property Law was also passed, declaring property left from ethnically cleansed Palestinians as legitimate for Israelis to acquire. This violates the Right of Return, a UN resolution upholding the right of refugees to return to their homes. Despite thinking of itself as champions of peace, the UN does not want to start an operation to enforce this resolution in Palestine.
The ethnostate would also fulfill its role as a Western outpost in Asia, just as Herzl wanted. It invaded Egypt in 1956, occupied Gaza and the West Bank from Jordan, and the Golan Heights from Syria in the Six-Day War in 1967. Sinai, conquered from Egypt after the 1967 war, was completely returned by 1982 as a result of the Yom Kippur War of 1973.
