Every last Jew removed themselves from Gaza in 2005, and within weeks, Hamas rockets began to rain down on Israel– Lesson learned! Hence the walls, check points, and the legal weapons blockade. Even Egypt built a steel wall to keep Hamas out.
Egypt banned Hamas and branded it a terrorist organization. Egypt even build a steel wall between Egypt and Gaza after Hamas was elected, to keep Hamas terrorists out of Egypt. You routinely condemn Israel for enforcing the blockade, and ignore the role of Egypt, which closed the southern end of the Gaza Strip to enforce the weapons blockade.
Jordan banned Hamas in 1999. In 2013, Jordan rejected requests to allow Hamas to return.
Hamas and Lebanon’s Hezbollah disagreed and were fighting with each other in the Syrian Civil War (Sunni/Shiite conflict).
Syria says- Hamas is an uninvited guest
Saudi Arabia says they will arrest Hamas members on the spot
