heatherrae said:Then he should be impeached for lying to Congress and submitting false evidence. We don't want to set a precedence of trying presidents for murder for going to war just because the war ends up being unpopular. That would be a really BAD decision.
In your scenario, it seems like he isn't truly held accountable for his actions.
The justification would not be that the war is unpopular. The justification was that he knowingly submitted falsified evidence. BTW, I have no idea if he actually did. It would be for the courts to decide.
