"fulfilling Obadiah AND Ezek. 25"

 
David,
 
If in fact Sharon is planning to fulfill God's will by annihilating the Palestinians, it would certainly line up with Ezek. 25:14.
 
Ezek. 25:14 "I will lay My vengeance on Edom by the hand of My people Israel. Therefore, they will act in Edom according to My anger and according to My wrath; thus they will know My vengeance," declares the Lord GOD.
 
God will use His people Israel to accomplish His will, whether Sharon realizes it or not.  We know that all prophecy must be fulfilled exactly, so this would seem like a plausible scenario.  And as you said, it would be a reason for all nations to come against them. 
 
I am also including a small portion of an article (from Cutting Edge) which indicates that Israel is already in possession of the "fire" weapon. 
 
Here's the article
 
The United States and Israel do possess a "Fire" weapon of mass destruction, and we believe this is the weapon Israel may use to achieve God's pronouncement of the doom of His judgment as described in Obadiah 15-18. This weapon is called the "Fuel-Air" bomb, and it was devastatingly used during the Gulf War. In fact, one of the most vivid pictures taken of that war depict a miles-long column of Iraqi vehicles that was totally annihilated, and blackened, by the Fuel-Air bomb. Every person in every vehicle was not only killed, their bodies were charred and blackened beyond belief. News reports said that over 1,500 Iraqi tanks, armored vehicles, jeeps, ambulances, trucks, and automobiles were annihilated by these Fuel-Air bombs. The soldiers operating these vehicles were totally annihilated in seconds, and their bodies were charred and blackened beyond belief.

A Fuel-Air bomb operates very simply. "Fuel-air explosives form highly gaseous mixtures which, when detonated, produce much more blast than fire. For their size and weight, they provide a much larger blast than any other weapon except for nuclear devices; in fact, the blast can mimic a small nuclear explosion ... Some are launched from aircraft, others from helicopters or ground vehicles."

Thus, if the goal is to annihilate an entire city within minutes, the Fuel-Air bomb would be the perfect weapon to employ. It can be launched from aircraft, helicopters, or even ground vehicles, as the above quote tells us. Thus, Israel could deliver this Fuel-Air bomb from a variety of launching platforms, thus making it more likely they could cover all the target sites at once. Palestinian cities would explode as if they were hit with small nuclear devices, but they would largely be destroyed by blast and fire, instantaneously.
 
Obadiah 1:18 "And the house of Jacob shall be a fire, and the house of Joseph a flame, and the house of Esau for stubble, and they shall kindle in them, and devour them; and there shall not be any remaining of the house of Esau;" for the LORD hath spoken it.
