Israel has already done that to Palestine, many decades ago, but they failed to do anything like the Marshall Plan to invest in the occupied lands and create a lasting peace.
If we hope to learn from WW2, we should consider the postwar history of Eastern Europe. Like Israel, the Soviets also failed to invest in the lands they occupied, instead trying to suppress rebellions with violence. Now all of those nations are Russia's enemies.
Don't know about Israel, but you definitely know nothing about the Soviets.
Soviets occupied lands more developed than them. They did not fail to invest, they looted the lands, for example the Uranium from Czechoslovakia [1].
