I think he already told you in that same post "what the hell to do", according to previous politics in this topic, that if he named probably he agree with.
To spell it out: sabotage the regime as hard as possible, incite a revolution and try to induce the internal collapse of the regime, do a lot of propaganda, infiltrate people, apply strong sanctions to weaken the regime further, and in the end fight and win the war in the commercial/political ground.
That seemed like a good plan, but it doesn't look viable after the escalation.
I suppose now there will be blood, the blood of the allies, probably South Korea and Japan.
Perhaps a direct confrontation with a high loss of life is unavoidable. (I don't think so TBH)
