A couple of good ones:
“You cannot allow any of your people to avoid the brutal facts. If they start living in a dream world, it’s going to be bad.”
This is the attitude that got him in trouble with the Obama administration.
“I’m going to plead with you, do not cross us. Because if you do, the survivors will write about what we do here for 10,000 years.”
There'll be survivors? If this had been the attitude in Afghanistan and Iraq, those wars would be long over now.
