Israel's schizophrenic justice

Nazareth court denied the petition by captured Hezbollah’s fighters to be treating as POWs rather than criminals. The court called Hezbollah “Iranian assassins.”
If it looks like a duck and flies like a duck, then before the law it is a duck: but Israel refuses recognizing Hezbollah as a legitimate military group.
If Hezbollah is a bunch of Lebanese criminals, Israel had no right to bomb the country of Lebanon over their mischief. If they’re Iranian proxy, as the Israeli court declared, then Israel have to retaliate against Iran.
