in Gh 's opinion an appropriate response would be.."oh look they killed 20 of us, lets kill 20 of them" and so on and so on and so on, so it will never end.
Better the Israelis kill hundreds more in retaliation, so that eventually Hamas,(or the Palestinians) wise up and wonder if it is really in their best interests to continue on a course which means the assured destruction of their entire populace. Said it before and will say it again, woe be to those that tweak the Israeli's nose... YOU DO NOT MESS WITH THE ZOHAN!!!!
