Nothing to suggest he is a war-monger.
He recently said that the current gov is not doing enough to prevent North Korea from attacking the south. He suggested concessions be made so they don't attack but then he said if they don't accept that other means may be necessary. Sounded a lot like war threats. Then again, his opponent accused him of "siding with the enemy" (North Korea) so who knows? It's pretty crazy everywhere right now. Every nation is polarized and I don't think this is a good thing!
