Fox News’ Tucker Carlson’s opening monologue Monday night warned the U.S. against intervention in Syria.

The Daily Caller co-founder noted that there has still been no proof that Bashar al-Assad was behind the chemical attacks against the Syrian people, explaining that such attacks would be counterproductive to Assad because the U.S. was planning to pull troops from Syria.

“The story, it turns out, was propaganda — it was designed to manipulate Americans, just like so much of what they say,” Carlson said of last year’s chemical attacks in Syria. “We’ve seen this movie before and we know how it ends.”

Assuming Assad was responsible for the attacks, Carlson questioned if it “would…be worth starting a new war” over.

“Overthrowing Assad’s regime in Syria would cause chaos,” he said. “Many thousands would die and, in fact, we might likely see the genocide of one of the last remaining Christian communities in the Middle East. And we ought to care about that. Some of the dead, of course, would be American serviceman. A new war would cost us tens of billions of dollars.”

Carlson also challenged the establishment media’s assertion that the United States cannot tolerate the attacks on the Syrian people and must respond accordingly.

“We do tolerate atrocities like this all the time,” Carlson argued. “For example, there’s a devastating famine killing children in Yemen right now. The Saudis are causing that famine.”

The segment also torched the idea that the rebels in Syria are moderates and that a democracy would magically appear in Syria if the U.S. intervened.
