The murder of Gazans and Palestinians in Gaza and the West Bank is totally unacceptable, and war crimes, however the murder of citizens of otehr countries e.g the EU should be an act of war by those countries. We need to declare the IDF a terror group and sanction every member.
When the decide to return to their home countries and families they should face arrest at the airport, detention and deportation to the Hague, then prison and a massive fine etc for what they have done, they are ALL guilty either directly or by association.
