Let's say you, Sam, own a large farm. And somewhere on that farm, coincidentally, is a large deposit of naturally-occurring "Roundup". As long as it stays where it is, everything is fine. But if it got into your fields, your crops would mostly die.
You have several neighbors, many of whom are basically friendly to you. You also have one neighbor who also has fields, who directly competes with you. His name is Russel.
You and Russel both know that using Roundup on each other could kill each other's crops. So you have a mutual agreement to never use Roundup... but just in case the other guy does, you build up a pretty big reserve to use in retaliation. Just in case.
That pretty much describes the "cold war". And it wasn't irrational. It was stressful but it did work.
Now along comes some insane manager of your farm, who decides Russel isn't so bad after all. You, the owner (The People) know better, but that's the line your "manager" (President) is selling you.
Question: even though you are not actively in conflict, do you sell shares in your Roundup mine to Russel? Especially when you know he will in turn sell it to other neighbors who are even less friendly?
It would be IRRATIONAL to do so. It would be BETRAYING your farm and your family.
But that's just exactly what the Clinton Foundation helped do.
It's not fucking rocket science. Nor is it paranoia.
