Fairly self-explanatory slide I used in the original brief I delivered for the Office of Force Transformation. Wasn't a cornerstone slide or anything like that, but I did have it in for certain audiences.
Basic notion is to show that the SysAdmin activity really started about the same time (mid-1980s) when Soviets were deep into their withdrawal from mischief-making in the Gap (curtailing or ending aid to Countries of Socialist Orientation) as part of the Gorbachev-led rethink of foreign policy and relations with the West.
The first great SysAdmin op, in my mind, was the escort ops during the "tanker war" between Iran and Iraq. It was rather purely designed to be a system-stabilizing effort and it worked magnificently. After that, we're into the sheriff work: arrest Noriega, oust Iraq from Kuwait, stabilize Somalia, the Balkans stuff, then Afghanistan-Iraq-and-associated-GWOT (as it was then known: global war on terror).
Meanwhile, the Sovs fall off the map and the only thing capturing the Leviathan's long-term attention is the possibility of casting China as a semi-hostile threat of "near-peer" status (remember, this is before our growing financial connectivity with China took off or became widely recognized).
I remember this chart as a 2002-2003 slide.
