The origin of settlements
Someone pointed out to me in the comment section that Kfar Darom was actually built in 1946 (according to the Jewish Virtual Library, "to prevent the British from separating the Negev from the Jewish state") , abandoned in 1948, and re-established (again, the JVL says "reformed", that it was never abandoned) some time after that as the Kfar Darom of the recent past.
"just a comment about kfar darom: it was a zionist kibutz built in 1946. Abandoned in 1948 after it was besieged by the Egyptian army. A settlment carrying the same name was built in 1989, but as far as i know, they had no connection to the pre-48 settlers. "
Of course residents of Dair al-Balah say many of the inhabitants remained well through the '50s, even under Egyptian rule.
Brings up the interesting debate about the origins of the settlement movement. Essentially, Israel itself was founded on settlements. Many settlers I've spoken to consider themselves "pioneers" establishing "villages" or Kibbutzim and tell me that they have gotten a bad rep in the media as "agressors and occupiers". Does that exhonerate them? I think not.
It seems that a thin red line was drawn somewhere at some point, and suddenly some kind of status quo was reached where it was no longer acceptable, at least in the eyes of the international community, to used this method of "pioneering" on other people's land to expand the borders and claim to your state (See: native americans. Also see: facts on the ground.).
