Why? To make Henry feel relevant? He is so 30+ years ago.
Yes, he’s older than dirt, but things are the way they are today, because of the decisions and policies made those 30+ years ago. Kissenger was a major part of many of those decisions. He’d be aware of the changes which have taken place in the minds, hearts and policies of nations and world leaders over the years. He’d know what their goals were, then, continue to be now, or what changes may have occurred over the years.
Kissinger was very much a part of middle east events back in the day, also. He is still frequently called upon to work on a special assignment from time to time.
I’m sure Trump realizes that since Trump has a few years on me.
It eill be interesting to see who else he consults with for a well rounded education.
