This is a credible threat considering how they trashed the Israeli embassy earlier this month while the Egyptian army stood by and watched.
And in case you haven't noticed, the Egyptian street - actually the Muslim Brotherhood and their salafist allies - pretty much run Egypt at this point.
The report is from the Fars News Agency:
According to a report by Palestine al-Yawm (Palestine Today) news network, the young Egyptians have posted a request on their Facebook webpage and blasted Barack Obama's speech after his presidency in Cairo in which the US President pledged a new approach towards Muslims.
They said that the threat by the Obama administration to veto the Palestinian bid for UN membership revealed the realities about Obama and the fact they "he is a liar and is no different with his predecessors in supporting Israel and blatant violation of the Arab nations' rights".
The Egyptian youths said the attack on the US embassy would serve as a strong message in response to the US hegemonic policies.
They further warned the US to refrain from vetoing the Palestinian bid, saying that such a move by the US would encourage violence in the world.
Fortunately, it may be while before the resolve of the protestors is tested. It is likely that a Security Council resolution will be delayed while Israel and the Palestinians are forced back to the negotiating table. How long that will last is unknown, but it will certainly be a matter of months before the SC takes up the issue again.
