To where exactly? To Sderot, to camp out in the hopes that Gaza would refrain from firing rockets for fear of hitting a white helmet?

Or into Gaza, where they would... Do what exactly? Stop the rockets and arrest the terrorists? Just as Israel does, but without any collateral damage, or dead civilians I suppose. (Because the UN soldiers are famous for risking their lives to defend someone else's country... Famously ineffective and for their lack of commitment to any task they're given.)

Can you point to an example where sending in UN soldiers helped anything?

This has been tried before you know. Recently in Lebanon for instance. To say it was unsuccessful would be a gross understatement.

Why/how would UN troops who have no reason to endanger their lives for someone else's country, who have no intelligence network in place at all, and who don't even speak the language, do a better job of demilitarizing Gaza with less casualties than Israel?

Why would Israel want to entrust their security to an organization that's failed to do exactly that every time they're deployed to Israel's borders during a conflict?

When has this idea ever once worked out for the better?

And people wonder why it concerns Israel ?
