He's an idiot for sure. His briefings are like watching WWE promotions.
My fear is he'll want to do some tough guy invasion cosplay and land marines on some island in the Persian gulf, which will be great pictures but leave the marines sitting ducks hence costing US servicemen their lives, just so Pete can look macho.
Its one thing to be pathetic, another to be pathetic and have that cost others their lives. Hopefully the generals will push back. However, they've purged many of those who will push back leaving the yes men. Maybe one finds the courage to risk his command to say no. But they've constructed an environment where honest opinion will get you fired, thus my level of hope is low.
