Unlike Trump, Milley was doing his job, living up to his oath of office, while serving the country and the constitution. Your question proposes a false assumption that Milley was in someway subverting the chain of Jmcgg in the club feeling peculiar shirt, he wasn’t! He was acting in accordance with stated procedures as established for situations exactly like this. This wasn’t something done on the spur of the moment or in a vacuum. Milley was following established procedures that have long been in place while Conferring with the state department and the department of defense. Milley’s action was based on the fear that our own Dr. Strangelove, a man obviously delusional , despondent and unhinged, a president who had just called an insurrection to overthrow a duly elected government who now had the Chinese believing he was prepared to attack them as show of power in order to remain in office. This was a deranged president who had the means and the motive for calling a nuclear strike against China brought on out of despair and desperation, and completely in keeping with his action in all in an effort to hang onto power directly following a failed coup d’état. China made it abundantly clear to Milley that they viewed Trump’s inciting an insurrection and a failed coup as a very real and an imminent threat to China and in fact to the entire world! Milley was doing his job in descalating the situation by assuring the Chinese that they shouldn’t have any concern that President Trump would be calling a nuclear strike against them or any of their assets. To be very clear, Miley was focused on ensuring that there wasn’t a chance of any miscommunication that might result in a nuclear holocaust! If you knew history you would know this was somewhat similar to what happened with the United States during the Cuban missile crisis. RFK, on behalf of his brother the president, was able to meet with and negotiate a détente behind the scenes with a Russia agent rather than going through diplomatic channels that saved the world from a nuclear holocaust. It wasn’t wrong for Milley to speak with his Chinese counterpart as it was in fact his duty according to the Joint Chiefs of Staff.
