Trump Bungles First First Military operation in a military operation he approved over dinner. Previous Presidents would have sought extensive briefings in the situation. But Trump approved this operation without the in depth consultation with security and legal experts over dinner.
This operation was approved by Trump at a dinner with "Mad Dog" Mattis, Trump's Defense Secretary. Also present were Jared Kushner and Steve Bannon.
As described in this NPR report Steve Bannon was Elevated By Trump to sit in on the National Defense Council while demoting the director of National Intelligence and the chairman of the Joint Chiefs of Staff.
The military operation in Yeman in which the New York Times article described this Disastrous Raid said there were numerous mistakes and miscalculations - everything that could go wrong did.
The cost from Trump' Raid was high. An American commando was killed. A 75 Million Dollar aircraft was lost. There were high civilian casualties including an 8 year old girl.
Many analysts say this raid, because of the high civilian casualties in this tribal area, actually resulted in more enemies for the United States not less.
