Rothbard's "The Libertarian Forum" blamed the Middle East conflict on Israeli aggression "fueled by American arms and money". Rothbard warned that the Middle East conflict would draw the United States into a world war. He was anti-Zionist and opposed United States involvement in the Middle East. Rothbard criticized the Camp David Accords for having betrayed Palestinian aspirations and opposed Israel's 1982 invasion of Lebanon. In his essay, "War Guilt in the Middle East", Rothbard states that Israel refused "to let these refugees return and reclaim the property taken from them". He took negative views of the two state solution for the Israeli–Palestinian conflict, saying: On the one hand there are the Palestinian Arabs, who have tilled the soil or otherwise used the land of Palestine for centuries; and on the other, there are a group of external fanatics, who come from all over the world, and who claim the entire land area as "given" to them as a collective religion or tribe at some remote or legendary time in the past. There is no way the two claims can be resolved to the satisfaction of both parties. There can be no genuine settlement, no "peace" in the face of this irrepressible conflict; there can only be either a war to the death, or an uneasy practical compromise which can satisfy no one. That is the harsh reality of the Middle East.
