"In other words, Hamas has not carried out an unprovoked attack throughout the period of the cease-fire."

By noticing what you have omitted, it seems that your contention is that *any* attack launched by Hamas is justified because of provocation. You have spoken nothing about the tactics by which the two sides attack each other. What you are saying, or perhaps attempting to avoid saying, is that Hamas is justified in sending rockets at civilians because Israel broke the ceasefire first. That can be the only conclusion from reading your point #2 above.

If this is your position — and I fully expect that either you will excuse it or you will distance yourself from that interpretation through equivocation — I wonder if you are aware that such reasoning would also excuse not only any suicide attack against civilians anywhere, but also any attack made by Israelis against anyone, for any reason.
