CNN has a good response to Trump's comments

A more judicious initial White House response to the raids might have avoided the current controversy. But its frantic spin was inevitable, since Trump declared while B-2 bombers were still aloft that Saturday’s mission was a total, overwhelming success. Any contrary evidence would mean an embarrassing reversal and challenge his ego and credibility.
But the hyper-emotional response to honest questioning over whether Iran’s nuclear program has truly been wiped out makes the White House look defensive, raising doubts about its truthfulness. And it is distracting from aspects of the mission for which Trump can claim credit – a flawless round-the-world bombing raid with no US casualties and his effective pressure on Israel and Iran to stop fighting as well as his success in not being pulled into a longer war.
Contrary to what Hegseth claimed, it is not unpatriotic to report information confirmed by administration officials questioning the extent of the damage to Iran’s nuclear program. And no one is attacking the pilots of the B-2 bombers who undertook the hazardous multi-hour mission. The tone of media coverage of their efforts has been marked by marveling rather than criticism.
The issue is whether the bunker-busting bombs, used in action for the first time, really did penetrate the Fordow nuclear facility, buried under hundreds of feet of rock and cement, and destroy centrifuges that spin uranium. And it’s about whether Trump is truly fulfilling his duties as president if he ignores any evidence the objectives were not fully met.
I can't imagine how someone advises him - he does not seem like the kind of person who listens to advice or different opinions - and he does not seem like the kind of person who likes to be challenged and to be told he's wrong.
