This is the silent warning that is permeating across the border from the scene of Cairo's chaos into Israel this week.
Many Israeli leaders fear that the Cairo uprising against President Mohammad Morsi may enable extreme Islamist groups to launch attacks into Israel from Egypt or the Gaza Strip, thus threatening Israel's stability and further denting the historic Egyptian-Israeli Peace Treaty.
The Israeli Foreign Ministry is refusing to allow the staff of the Israeli Embassy to return to Cairo until the security situation in Egypt improves.
Former Israeli Ambassador to Egypt Eli Shaked stated that the instability in the region is "bad for Israel and bad for the Middle East." Already Israeli officials are concerned about being dragged into Syria's ongoing civil war, which threatens daily to spill over into northern Israel. Israel simply cannot afford a new crisis with Egypt, said Shaked.
One can only assume that any diplomatic crisis with Egypt would lead to the fracturing of the peace accord which has served as a strong anchor of stability for Israel in the region.
Israeli Prime Minister Benjamin Netanyahu said that "like everybody we are watching very closely what is happening in Egypt," and Israeli military officials have since moved forces into the border area near Gaza in order to help contain any militant threats which may arise.
