Eliot Cohen: “To friends still thinking of serving as political appointees in this administration, beware: When you sell your soul to the Devil, he prefers to collect his purchase on the installment plan. Trump’s disregard for either Secretary of Defense Mattis or Secretary-designate Tillerson in his disastrous policy salvos this week, in favor of his White House advisers, tells you all you need to know about who is really in charge. To be associated with these people is going to be, for all but the strongest characters, an exercise in moral self-destruction.”

“For the community of conservative thinkers and experts, and more importantly, conservative politicians, this is a testing time. Either you stand up for your principles and for what you know is decent behavior, or you go down, if not now, then years from now, as a coward or opportunist. Your reputation will never recover, nor should it.”
