Which is both deplorable and fails to justify the killing of innocents.

I've dug bodies out of bombed buildings and am no fan of real life bloodied and burned bodies - whether the cause is Hamas, Israel, or an earthquake.

Sometimes you have to seek a solution when someone commits an act of war, like murdering 1400 civilians--brutally--and taking over 200 people hostage. The goal is to make sure this never happens again.

Sure; Cause --> effect.

> like murdering 1400 civilians--brutally--and taking over 200 people hostage.

Was there any prior cause for this, or did this just happen "out of the blue" with no prior provacation and no warning from various citizens of Israel that such an event was inevitable if the state continued down certain paths of action?

Somebody is confusing Hamas with Palestinian civilians.

He's not confused, he's deliberately conflating them because he wants violent retribution against a civilian population. It seems all the wrong lessons were learned from WW2. Instead of "never again" it seems to be "this time by us."

I think you missed the word civilians.

Half the middle east has the right to come to the US and murder civilians by your reasoning above.
