Granted. You get a good lecture on the Cold War, with a decent teacher that can truly explain it, and that will last exactly 2 hours, with no assassins or other harm that could come to you in any way, and the result will be where you can learn a bit on European History, as well as allowing you to leave the building where the lecture is taking place freely, and you shall bringyour lunchbox that has food and water to last the time, although that is not part of the wish.
But you’ll live a boring, boring life thereafter.
I wish for a bahsheep cushion. ^_^
