Hamas and the PA don’t control countries. They control internally occupied territories under military control of Israel (different degrees in Gaza and the West Bank), which controls all imports, exports, food, water, travel, etc of the Occupied Palestinian Territories. Gaza is literally undergoing famine extreme water scarcity, with extremely limited medical aid by the design of Israel. Israel has been in complete control, either internally or externally, of Gaza and the West Bank since 1967

International pressure is how this ends, like it did with South Africa
