You never know what your enemies will do until they do it. What is to stop Assad using chemical weapons in some last ditch effort to hold onto power and so he uses chemical weapons try and be an arab hero. He doesn't care if his army is smashed as a result if it will make him a hero back home and allow him to stay in power the result has been achieved. How does Barak know that if somebody attacked Iranian nuclear facilities they wouldn't retaliate with a chemical attack? What happens if Hezbullah or even Hamas got hold of some Syrian or Iranian chemical weapons and decided to make themselves a chemical weapon of some kind? Egypt is suspected of still having chemical weapons, what if they got a radical government who decided to use them? The only good thing Barak has done as defense minister is getting new hardware for the IDF like the deal where Israel would not only be allowed to buy install its own systems on the F35 but the bomb bays would be modified to carry Israeli made missiles rather than having to use American like all other buyers will have to do. Even the countries that invested billions in the F35 program are not allowed anything but off the shelf planes and cannot install their own equipment. Not only is Israel installing its own equipment but it is going to build the wings for a third of global F35 sales which will be worth billions to the Israeli defense industry and we have Barak to thank for that. He also negotiated a reasonable deal with Germany for the sale of a sixth submarine and he is getting the IDF more Merkavas and the new Namer APC. So on the business side of things Barak has been great when it comes to actual defense issues he has been average at best.
