Also “and margins” seems like a stupid thing to add. Margins are high during peacetime and wartime alike. And it’s not parallel to bribes / kickbacks which are corrupt and illegal. Margins are the natural outcome of capitalism + monopoly.
Having S Korean competition means those margins would likely drop over time.
