This is my personal opinion, so I will preface it:
The Egyptian passive-aggressive border enforcement and malicious compliance with Israeli requests for humanitarian assistance is really irking me.
It only served the purpose of maximizing the extent of injury and death the Israelis suffered in the attacks by denying them the "golden hour" of emergency medical treatment.
I wont go so far as to blame Egypt for aid and comfort to the terrorists by helping them maximize the casualties, but it sure looked that way from the outside.
If they intentionally did that, then they are no better than the terrorists who exploded the ordinance.
Israel Seeking to Land Chopper in Ras a-Sutan
01:21 Oct 08, '04 / 23 Tishrei 5765
(IsraelNN.com) Israel is negotiating with Egyptian authorities to land a Yasur transport chopper in Ras a-Sutan in order to evacuate the many wounded at that location.
Well you can clearly blame Egypt for supplying the terrorists in Gaza, in violation the the 79 treaty, of which the US is a party. Egypt is a party to the terror.
