He warned us about the emergent military-industrial complex. We didn't listen.
Dwight D. Eisenhower also warned his fellow Americans of what today masquerades as his own Republican Party when he said,
“If a political party does not have its foundation in the determination to advance a cause that is right and that is moral, then it is not a political party; it is merely a conspiracy to seize power.”
Ike's warning foresaw today's Republican movement that has hammered American democracy with first political capture, then regulatory capture, and now, under Trump, executive capture. This is the America I wrote of in a recent post,k "Attacked from Within, Attacked from Without."
BTW, the Eisenhower quote comes from a site named Verrit. It calls itself "media for the 65.8 million" a reference to the number of Americans who voted for Hillary Clinton.
