Could Amazon Buy a Country?

Amazon has more employees than a lot of countries have people (they would be the 171st most populated country in the world)... I don't know what the P/E ratio of a country should be, but $22B is 15 times the GDP of Saint Kitts and 50 times the GDP of Sint Maarten. They could legitimately find a government that is struggling with debt, and offer to buy half the land in the country with a condition of being recognized by the government as a sovereign nation.
