You guys are misreading the intent. This was a humanitarian gesture to encourage Palestinian unity and provide some relief to the civilian population of Gaza. Some transiting yesterday were patients in need of medical care that was previously denied. A lot of others were students. Egypt has also coordinated with the Israeli government and is denying goods transfer at present. That is hardly lifting the siege. It is opening a small gate for some minimal humanitarian relief only. All the stuff that Israel has prevented Gazan civilians from having is still prohibited to them. Some foodstuffs, cement, lumber for reconstruction, PVC for sewage treatment is all still prohibited or so high priced as a smuggled good, it is unavailable to the average civilian.
