He's respecting the culture..it's a sign of disrespect in the Japanese culture not to partake in the tradition.. a small glass of wine or in this case Sake isn't enough to affect anyone negatively.
In this case Korean culture for the literalists
Did you see him drink the entire glass? Everyone there is drinking at the same time.. it's a toast. In that culture it's the same as a handshake.. Trump knows this. I personally don't drink either but I've had a sip of wine on special occasions.. doesn't mean I lied about being a non-drinker. I just didn't want to look like faggot who ruined the moment. Trump ain't no faggot on the world stage. You not getting this situation doesn't make it fake. They didn't pass him cocaine, he had a sip of wine or champagne. Not exactly sure what the South Koreans drink on those occasions.
