What's the point of fighting in Iran if the US has betrayed its values? [View all]

The US has said for as long as I can remember that Iranian oil money supports terrorism. Now they are going to back off of sanctions? It's pathetic and weak. It signals two things. 1. Iran is winning because it's achieving its strategy. 2. The US stands for nothing. If the US truly has no values, there is no reason to be killing people. Step away from the war. Claim victory or claim defeat but stop fighting a pointless war. There is no reason for anyone else to die when Trump and the US government stand for nothing.
