In simple terms, this is a situation where you have two sides full of people willing to launch missiles at children. Until that dynamic changes, this is never getting resolved.
Imagine Nazis arguing during the Holocaust arguing that Jewish “terrorists” were also killing Nazis and that both sides were in the wrong, and nothing could really be done until the Jewish people stopped fighting their oppressors.
Fact remains: both sides are willing to kill children in order to advance their cause.
