It does matter if there was not an imminent threat. If no imminent threat then what he did was an assassination of a high ranking individual of a foreign government. In the past these types of actions started wars. He has almost started one but I fear this is not over. In the back of my mind there is this question: Has he made himself an assassination target? I hope not as this would most certainly start a war I fear. He has most certainly made our personnel in the area targets for retribution.
