"Jim Mattis: Duty, Democracy and the Threat of Tribalism
Lessons in leadership from a lifetime of service, from fighting in the Marine Corps to working for President Donald Trump"
What a shame that Mattis isn't supportive of President Trump. It is not Trump's fault that the enemies of America are so vile and vicious.
Mattis should be supportive of Trump and all he is doing for America in the face of all odds. Trump is a great leader and is developing many allies. So while Mattis' message sounds noble shame on him for not remaining a support to the President and for resigning when we need him most.
