@philmohun @elidourado @ATabarrok @tylercowen Two caveats:
1. If instead of buying Greenland, US wanted to buy some land in the middle of Denmark, *and* the US was a hostile power looking to put a mil base there, then security interests of all of Denmark should be considered
@philmohun@elidourado@ATabarrok@tylercowen两个警告：
如果美国不购买格陵兰岛，而是想在丹麦中部购买一些土地，*并且*美国是一个敌对国家，希望在那里建立军事基地，那么应该考虑丹麦所有国家的安全利益
