Obama has used the US veto in UN Security Council to stop Israel's illegal settlement building being condemned and sanctioned. Obama has used UN veto to stop Palestine being accepted as a fulll UN member. Obama has declared that US opposes the peaceful BDS movement and that USA will act against all who try to organize boycott of Israel's illegal settlement products and so on.

Without Obama's support, the occupation, ethnic cleansing and apartheid could not go on. To bring the occupation to an end, he would only have to stop using US veto in UN Security Council to "protect" Israel.
