"There would be people going apeshit here, we don't need another major oil crisis right now, it would screw with our "recovery"."
I see your point. If a radical group takes power in Egypt, then they could force the closure of the Suez, creating a gigantic crisis. And its closure would threaten Israel as well.
The last time Israel attempted to change its leadership, a major political figure was assasinated, FYI.
