What do you think WW2 was exactly, if not a literal attempt to conquer it?

You're arguing with a straw man. Nobody claims the EU had to do anything, it can ban people who live there from buying British things if it wants. But the idea that this will cause food and medicine shortages is simply silly - the rest of the world manages to buy these things without being in the EU so why does this story keep being promoted?
