I don’t think it’s healthy to be an absolutist about just about anything. The unattended consequences start to outnumber your ideals. If Israel hadn’t done after Hamas, Hamas would be empowered to keep doing it. The net effect would be more Israelis killed. Who knows, they may have been invaded by one of the several neighboring countries that would like nothing more than to destroy the country.

I think Ukraine is a better example though. I can’t fathom telling them they should try to get along with Russia. There’s the idea of being anti-war in general, and then there’s allowing a foreign aggressor to come in and take your country.
