Most Negative Western action of the Cold War?

So many to choose from...Surprised Operation Paperclip hasn't been mentioned yet, although Operation PBSUCCESS might be a better one.

The LBJ fanboys aren't going to like all this talk about Vietnam being the most negative action of the Cold War.

As an LBJ fanboy I'll readily admit that Vietnam was the most negative Western action of the Cold War. 2 to 4 million people died, all told. Nothing really compares to that.

Would the Phoenix Program constitute a part of the most negative action, or would it have to compete separately with the Vietnam tragedy for most negative action of the Cold War?
