At last week’s NATO summit, President Donald Trump denounced the allies for taking advantage of American taxpayers. Then he approved their latest subsidies. He even agreed to invite a military weakling, Macedonia, to join NATO, which will add yet another nation to our military dole.

When George Washington warned Americans against forming a “passionate attachment” to other countries, he might have been thinking of the Balkans. Indeed, a couple decades later, John Quincy Adams criticized proposals to aid Greece against the Ottoman Empire, which then ruled that region. America “goes not abroad, in search of monsters to destroy,” he intoned.

On into the 20th century, the Balkans were in turmoil. Germany’s “Iron Chancellor,” Otto von Bismarck, warned that “the great European War would come out of some damned foolish thing in the Balkans.” That’s exactly what happened in 1914.

It took decades and two world wars for the Balkans to stabilize. But after the Cold War ended, Yugoslavia, which had emerged from Europe’s previous convulsions, broke apart. One of the smaller pieces was Macedonia.
