Ha-ha. Nice name. Interesting you brought up Gaza. Another location from which Israel withdrew entirely, and Palestinians continued to attack Israel regardless. But be that as it may, there is at least no established international boundary between Gaza and Israel. There is one between Israel and Lebanon, and Hezbollah decided to breach it. Don't worry Israel doesn't need a proxy. It will go straight for the jugular.
