Rik, 
Neither you or I or anyone else here is clairvoyant and knows what is in Donald Trump's heart. None of us knows his most private thoughts, all though he does tweet what's on his mind frequently, we still can't judge whether he is repentant or unrepentant. Not 100% Which is  probably why Jesus also said a Christian has to love even our enemies.  Trump's words have at times been un-Christian and at other times he will need to actually have to order to kill our enemies, just like Obama did and every other President before has.  The Bible says that the governing authorities are  God's sword to keep order and punish wrongdoing.  At times even  the  'authorities' have done evil (Hitler, Roman Empire come to mind)  And it is then that  God uses other nations  to subdue and break lawless nations  apart.
