I really can't accept the justification for such a massive retaliation that's bound to have a huge cost in terms of civilian lives. This is no longer collateral damage - it's not like casualities are mostly Hamas combatants. Gaza is one of the most densely populated areas in the planet and for evey Hamas militant they hit, they will also kill at least a dozen of civilians that, until now, didn't represent any threat to Israel.
As for the Israelis, they will have to endure the consequences of electing such a reckless government.
When someone spends the last decade firing rockets at you that kill, on average about five people per year, it's very clear they are not really good at that. By making this disproportionate reaction, the Israeli government is not caring for the safety of their citizens - they are in more danger now than they ever were.
This ugly war is going to get far uglier.
There is no end in sight.
