Since when has Israel cared about "rules"? The whole framework of the Zionist mentality revolves around being excepted from the very "rules" that it tries to hold everyone else to. When it says it wants "new" rules of war, it really means it wants no rules for itself, and lots for everyone else. The only rules Israel has a problem with are the ones it doesn't make for itself, and when it can't investigate its own crimes it whines about anti-semitism and appeasement of terrorists. There ARE currently lots of laws concerning war, and asymetric and low-intensity conflict, which Israle is engaged in against a captive, imprisoned population in Gaza. Let's talk about NEW rules when you're ready to follow the OLD ONES. Of course, if Israel followed the EXISTING rules, there would be no insistance upon NEW rules for their idea of what's fair in war against those it believes are nothing but drugged cockroaches in a bottle.
