Summits between the leadership of the superpowers became major implements of public diplomacy from the mid to late Cold War. Success was measured in terms of agenda items secured, treaties signed, and who was tougher on whom. As in an international boxing match, non-aligned countries watched from the sidelines trying to discern which power was in the ascendant. Virtually all major arms control agreements were either initiated or concluded at a summit. In that sense, they were an important tool for sizing up relative intentions, and ensuring the Cold War did not become hot.

Summit is one of the weakest cards in the game to draw. For starters, it’s a 1 Op card: Nuclear Test Ban might be the worst event relative to its Ops, but no one is ever unhappy to draw it.
Worse, like Olympic Games, it has the strong possibility of losing you the game at DEFCON 2. Although it is not a guaranteed DEFCON suicide card, you would be foolhardy indeed to play this at DEFCON 2 unless you had a massive lead in regions.
More commonly, because of its very low Ops value, you might headline it if there’s nothing else worth headlining and you’d rather conserve your Ops. Alternatively, if you are absolutely desperate for VPs, Summit offers you the grim choice of a chance at 2VPs or nuclear annihilation.
