if countries were stocks, which would you buy and sell?

Pretty much as the title says - which countries would you buy and sell based on their growth / development prospects over the next couple of decades. Naturally, current base and prospects will be priced in - US would be very expensive, South Sudan very cheap, etc. Personally, i think Singapore or Denmark would be expensive but would give nice steady returns, while Vietnam would be a good option with growth potential. I'm a bit concerned about eg Bangladesh because of climate change, and others because of demographic concerns. Would probably sell the UK but that's probably been priced in since Brexit. Anyway, what do people think?
