Flooding “could severely damage some areas.”
Gee, what a shame that would be. It might undermine buildings and they couldn’t rebuild there. I repeat, what a shame.
My first thought was similar. So what if a few buildings collapse - it would probably bury some terrorists or some of their supporters. B-F-D.
Israel should be bull-dozing everything they capture with the intent to annex Gaza and turn it into a vacay spot.
