Or they should covertly start supporting the locals to get even with Israel.
Israel has no capabilities to fight an organised rival, we all know this after Lebanon war. Any country (Egypt, Turkey etc.) can easily take on Israel, if others give them support (covertly if they don't want to risk otherwise), but it needs atleast ONE country to sacrifice (taking on Israel).
The time of diplomacy has long passed. If we are not to stand against the tyranny, have no surprises if nobody stands for Pakistan when time comes. And wAllahi, this is the time if the Arab world has to neutralize Israeli threat. One cannot get any better chance than this.
I can almost gurantee you that if OIC borrow some balls and declare war on Israel if it does not withdraw, no western country will be willing to form a coalition with Israel.
But, it takes only one country to make the move, while rest supporting her (covertly if not overtly).
On the side note, expect nothing from Turkey atleast... its army has been completely neutralized by tyrant western nations. Turkish army wont allow/help anything that is remotely connected with Islam, tho salute to gallant Turks, who are great Muslims, but unfortunately their army is what controls everything and its majorily anti-islamic and threatens to oppress anything Islamic within the political arena of the country, thanks to AtaTurk for that.
Egypt on the other hand, having Hosni Mubarak's balls in America's purse, will never do anything (they are not even opening the border), unless Muslim brotherhood and the gallant egyptions rise and overthrow the puppet govt.
So chances are, Muslims are further divided, by everyone thinking that no powerful Muslim country have come forward to help other Muslims, while almost every western country is defending and supporting Israel in this massacre with U.S. surpassing all the tyranny.
The fault lies in the Islamic world for not standing (even if it does not have the capability) against the oppression of the Muslims in the hands of some tyrant nations.
