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.
Course Egyptians don't want Palestinians as Syrians don't want Iraqi refugees.
But in the mind of the peoples it's one more problem caused by Israel/Western. Egyptians don't want Palestinians on their borders but all the Arabs and Muslims around the world who see this on TV will say: "Poor Palestinians, look at what Israel/Western has done, once again" and will be then more receptive to the hating speeches against Israel/Western, radical Islam grows on these sort of TV images.
For example, do you know what answer some Senegalese converted to radical Islam? They say that they chose this way because US invaded Irak and Afghanistan. Do they care about Iraqi? about Pachtouns? They are African Peuls and the only thing which bind them with all of this is the anti-Western or anti-Western/Israel feeling.
Here, I speak about TV and about feeling, both of them are now international.
