After all this consternation from the right, what we are left with is this:
1) Part of Milley's responsibilities are to regularly consult with military counterparts in other countries to de-escalate tensions and avoid unintended military conflict spiraling out of control.
2) The US had intelligence that the Chinese military believed that Trump planned to attack China. (We can debate whether their fear was justified or not, but for this issue it does not matter as they had that concern warranted or not).
3) With full knowledge of top administration officials, and with many witnesses, Milley called his counterpart in China to assure him that their intelligence was incorrect and that Trump was not planning to attack them.
4) Credible rumors circulated amongst top Congressional and administration officials that Trump was prone to do something reckless. Pelosi heard these rumors. Again, we can debate whether they were legitimate or not; that is not the point. It is no secret that a lot of people, including people within the administration, were expressing concern that Trump was unstable and lashing out at everyone.
5) Pelosi called Milley to express these concerns, as she should have. Milley, as he should have, assured her that Trump was the sole authority on use of nuclear weapons and Commander in Chief, but he also reassured her that there were many steps within the communication process and that such would prevent any sort of hasty, unilateral action by Trump.
This is how I think all of us should hope that the process would work when we have the situation at hand as in December and January. No attack was launched, we cooled tensions, and allayed rumors and fears. It is time you Trumpsters set aside you loyalty to him and instead see the bigger picture that this was handled well and appropriately under all of the circumstances.
