Why is Israeli onslaught not being contained ??

An elected representative of the Palestinians in Gaza strip, the Hamas, even though everybody agrees is a terrorist group, should not be pounded as heavily by the Israelis armed forces as is happening now...  With 40 air strikes aimed at Hamas installations, 360 dead (50 civilians) and over a thousand injured, the call for revenge of these killngs is getting sharper day by day. 

Maybe for the Israelis, the patience is running out suffering Hamas' missile attacks into Israeli territory.

With Israeli PM saying this is just the beginning, it is not known whether these attacks are for the electoral benefits for Israeli ruling party ..

The cycle of violence and revenge is just continuing with no end..
