If these images are true, then the image of a beautiful and prosperous Gazan strip came during the Israeli "occupation." The desolate Gaza came after Israel forcibly removed her citizens from the land.
To take the image at its word is to understand how much better life would be if Israel just took the whole fucking thing over again.
It also shows that the broad demonization of "colonization" is bullshit -- even though the Israelis aren't colonizers.
Sometimes, outside forces know better than you.
