After 75 years, Gaza's "refugee camps" were full on cities and towns, with shopping, hotels, malls, hospitals, infrastructure, etc. I suspect this coming refugee camp will allow no permanent structures. It will be a camp, with tents. It will stink. It will be hot, cold, wet. It will be miserable. Like a refugee camp is expected to be. People will want to leave. To anywhere.
And your point is…?
