the first thing out of the Army dude's mouth was a lie. He claimed that the US has been in the middle east to destroy ISIS. That's a lie. Also, nowhere do either of them indicate that this should not be Donald Trump's decision, i.e., to go to war with Iran. They make it sound like it's totally Trump's decision (because he's the commander of the military) and that he's being led to war by his advisors, specifically Bolton. This ignores the fact that the president cannot declare war and that Trump literally campaigned on a war with Iran in keeping with the de facto American/zionist policy of remaking the Middle east. They also leave out the fact that the U.S. IS illegally and un-constitutionally waging an economic and covert war against Iran now, a major military operation would simply be a major advance.
So what did they really say to those that watch Fox news, primarily conservative Trump supporters? They said the US is in the middle east to fight ISIS and Trump is being led by Bolton to go to war with Iran which will hurt his reelection chances. So in effect, Carlson gives cover to Trump and those wanting war with Iran by perpetuating the broad false narrative about fighting ISIS and that the president, as commander in chief, can go to war at any time to protect the country without the approval from Congress. He also gives cover to Trump by continuing the bs (same bs used under Bush and Obama) that it's not really his fault, it's the deep state that is pushing this.
Personally, I see more harm than good in what they're saying.
