You know, the usual sort of museum experience.
As interesting as this is, it's also tragic if you think about the vast resources humankind has spent on building terrible weapons and defenses against those weapons. Imagine how much farther we would be ahead as a society if what was spent on the cold war was spent on solving the world's real problems instead - climate change, poverty, hunger, and so on.
Even more tragic is that this expenditure continues, particularly by the United States, even though the cold war is over. Those of us who thought the end of the cold war meant we could move on from spending trillions on weapons were obviously rather naive.
