Why, wondered President Donald Trump, have Washington politicians decided to risk American lives to defend Montenegro? It's a good question. He should ask the president who oversaw Montenegro's entry into the alliance: Donald Trump.
The president went on Fox News and agreed with host Tucker Carlson's question: “Why should my son go to Montenegro to defend it from attack?” The proper answer is the latter shouldn't. The U.S. government should risk its citizens' lives and squander their wealth only to protect their nation, not to conduct grand foreign crusades, even for Montenegro.
Indeed, the Balkan nation is a good example of the folly of NATO expansion. The alliance was created as Europe fell into the Cold War. The purpose was to prevent the Soviets under Joseph Stalin from doing what Adolf Hitler attempted: dominate Eurasia. Hence, Washington focused on protecting the major states of Western Europe.
