What is the consequence of if one assumes the land belongs to somebody other than Israel?
Find out who actually owns the land under actual International Law, not just what a bunch of angry politicians at the United Nations may rant about.
The Israelis who actually own the land should not be fought over it. Peace should be the default choice, not rebellion. The people it hurts the most is the Palestinian Arabs. By wrongly thinking they were oppressed, when this was only a 20th Century antisemitic fiction and they never ruled the land ever in history. This works to guarantee endless conflict, hatred and bloodshed. And the terrorists place Arab children in harms way.
If you promote a false narrative, that risks leading to violence. Yes, that began in an antisemitic way, but it is worse than normal antisemitism, as it also causes suffering to Arabs as well. Learn the full history of the Holy Land. Don't promote violence and endless conflict. It hurts both Jews and Arabs.
Discuss the advantages of peace. That way peace may flourish. May it soon be so, by the grace of God.
