The Middle East has plenty of oil and gas, but water is in short supply. No country feels the lack of a natural water supply like Israel. Israel has only one river, which it has to share with Jordan,and that is the River Jordan which is being gradually depleted as it empties into the Dead Sea. Some natural water comes from the Syrian Golan Heights captured in the 1967 War, and desalination of sea water is another source but it is rather expensive. So, Israel is forced to import water, almost close to half of what it needs, from Turkey.
Israel is highly advanced technically. It also has thriving agriculture with migrant workers from Africa. Both sectors use large amounts of water. The rate of water usage constantly increases, hence the constant need for more water. The adjacent state of Lebanon has fairly abundant water resources.
Israel is probably the fourth most powerful country in the world. It has nuclear weapons, a delivery system Jericho rocket range of 11000 kilometers, and a sea based missile system on diesel submarines supplied by Germany. It also has an anti-missile system, called the Iron Dome. It produces its own tanks, The Merkawa; its own jet fighter, the Kfir, plus other high tech weapons. It also gets most of its modern jet fighters from the US. The Israeli Defence Forces are highly trained and motivated. So Israel has everything except the water, and that is the problem. War over water is inevitable; the Litani River of Lebanon is in play.
Israel wants to play the victim, it wants to claim it had no choice. Its main opponent is Hezbollah of Lebanon. Hezbollah is well armed with modern weapons, including missiles which can reach any part of Israel. Hezbollah is presently helping President Assad of Syria. They are battle tested and will fight an asymmetrical war. The outcome could be very uncertain. Only time will tell.
