The NBA star bows his head to the Regime and Kim Jong-Un and threatens the already frail diplomacy between the US and North Korea. He uses this severity to do his own bidding with the Regime rather than leaving the painstaking task of making diplomatic peace to actual diplomats. He claims that Kim Jong-Un is a nice guy, despite ordering the execution of his own family. He rather defend a Regime than America, which is simply wrong. His actions are ill-minded, and the American people are tired of this.
Question his actions because he can make a situation that is already fragile, worst.
