Yes, they do believe all his lies.
And they don't care That makes them members of the Trump cult
All president's lie. I refused to vote for Reagan because of his lies about a balanced budget.
But Trump's MO makes his unique. He actually creates crises just to entertain his faithful, and then he claims to solve them, thereby saving the world from certain destruction, only to just walk away and leave them smoldering. North Korea was the most entertaining.
The problem with Iran is that his advisors really do want a humanitarian crisis in Iran will destabilize the regime. This isn't just another Donnie Two Tone bait and switch University thing. Bolton and Pompeo are dangerous people. What is more likely to emerge in Iran is a MORE authoritarian state rather than some flowering of democracy. It's as naïve as Obama's arab spring. And Netanyahu is hardly a voice for reason and peace.
