Still more important are the TV images of this event. I think the impact will be very strong in the international Arab and Muslim community, giving in the opinion something like that: "Israel/Occident are making the habitants of Gaza poor and refugees in their great Arab Muslim friend, Egypt".
Except Egypt hates the Palestinians too.
We shall see how Egypt handles this. I predict they will end up resecuring the border within the week. This won't last. Egypt doesn't want a few million Palestinians in their country looking for work/starting up sh**t. They (and many others) will try to pass the "problem" back on to Israel, but nobody is stopping the Egyptians (or anybody else for that matter) from sending food and medicine and what not into Gaza.
