The Department of Government Efficiency, one of Trump's election promises, is set to be established with the aim of increasing government efficiency by reducing bureaucratic costs, ending wastefulness and restructuring federal agencies. Musk, Trump's biggest election financier, is expected to head this ministry. So not only is he the richest man in the world who dreams of going to Mars, but he is also an aerospace mega-investor who will also carry considerable weight in the Trump's second term.
As I understand it, Musk's main criticism is the F-35 project model. This is not something that is subjective, it is a problem that has been voiced many times, including by the US Air Force, and has been discussed for years, but whether unmanned combatant aviation can become the dominant factor as soon as it is said to be is open to further debate. But in general, it is a statement that should be taken into account. Btw, LMT plummeted deeper, after Musk's tweet. He may have short sell. lol
