Sir,
I don't recognize your Jesus. That is the simplest way for me to say this. You say that God has given the leader of our country the authority to wipe another person off the earth by whatever means necessary. You acknowledge that this includes means that would annihilate millions of lives. Eliminating exponential scores of people alongside the man who has cruelly punished them is no sort of justice. It surely isn't in the realm of anything one would call pro-life. The act is evil, pure and simple and you are saying that God is blessing this: a means of death and destruction, tools full of utter disregard for humanity, and weapons that could wipe life from the face of God's good creation.
I do not recognize your Jesus. I don't hear your Jesus blessing peacemakers or loving his enemies. I don't see him offering forgiveness or weeping over the lost. I don't see him laying down his life for others. And I'm sure you might point out that Jesus once said that he would bring a sword. But this, nuclear destruction, is not what he was talking about and let's not pretend you think that was what he was talking about either.
Your Jesus is not the Prince of Peace and Son of God I see in the Bible. He is a cartoon cowboy riding a weapon of mass devastation in a Kubrickian farce. Your Jesus screams "MAGA!" and reigns over the Kingdom of the U.S.A. rather than the borderless Kingdom of God. Your Jesus blesses excruciating death rather than being one who overcame it.
