What do you mean unpunished? Based on the history of Israel and Gaza, the attack on Israel was the punishment. So beyond the fact dropping thousands of bombs is absolutely unacceptable, any lethal retaliation is not going to help the situation. It's an emotional reaction with devastating consequences.

This is the same excuse Turkey uses when people bring up Armenian genocide. If we think really hard and cannot find some in-between solution, does that mean the genocide is justified? Is it our job to, or are we even capable of, finding a solution? Is it not the job of politicians or some other professionals?
