A ground campaign is imminent but the difficulty of that ground campaign will be on a level that is fairly similar to the combined threat that the US faced in Vietnam and Iraq.
Hamas hides amongst civilians, they fire rockets from civilian buildings and then live amongst civilians and they're not going to stop. They're going to try and kill as many Israeli soldiers as possible regardless of the methods used by the Israeli military and there will be civilian collateral.
Why is it so difficult to criticise Hamas who are driving the continuation of this war yet it's so easy to send Israeli soldiers to their deaths?
Forget the ground war, Hamas must stop and Israel must stop, period.
