Yes these, what happened to the other border? Egypt?
As yes , you mean the single crossing at Rafah that is run through treaty by joint operations by Egypt Israel the EU and the PA .
Damn Frag thats a bloody good question . That really needs some thought to answer .
Well lets see , why isn't aid coming up from that crossing ?
Errrrrr......before the elections it was closed by israel nearly 90% of the time , since the elections it has been closed entirely by Israel and the EU .
Like you say its a piece of cake for their arab brethren to ship stuff up from Egypt , if the crossing wasn't closed of course .

Would you like to try another question ? perhaps one that makes sense .
