Sorry, Charlie. The entire system has, indeed, tanked.
When one cuts a femoral artery, the blood drains from the entire body even though it's a relatively small cut.
When one has liver cancer the entire body dies. If the engines on an airplane fail, even though the rest of the plane is in fine fettle, the entire plane comes down.
A 180 pound weight on the shoulders weighs down the entire person.
And when the executive part of the body is ignorant, weak and blindly follows a failed ideology the entire body acts foolishly. It affects even the healthy, reasonable parts.
