Israel is engaged in a military occupation of the West Bank.
Israel . Israel 's occupation of the Palestinian territories is the world 's longest military occupation in modern times . `` Palestinian territories '' and `` occupied Palestinian territories '' ( OPT or oPt ) are descriptions often used to describe the West Bank ( including East Jerusalem ) and the Gaza Strip , which are occupied or otherwise under the control of Israel . Israel occupied the territories of the West Bank and Gaza Strip in the Six-Day War of 1967 and has since maintained control . The cost of the occupation for Israel over four decades ( 1967 -- 2007 ) is estimated to amount to $ 50 billion . In 1988 , with the Palestine Liberation Organization ( PLO ) intention to declare a Palestinian State , Jordan renounced all territorial claims to the West Bank , including East Jerusalem .
