Last Friday the Serbian government sent a train emblazoned with the words "Kosovo is Serbia" to the border between Kosovo and Serbia, where it was stopped by Kosovan security. In response the Serbs amassed a force of 60,000 soldiers on the frontier and have pledged to invade Kosovo if any Serbs are attacked. They have failed thus far to move the train across the border, but the standoff continues.
Though Serbia has never acknowledged the independence of Kosovo (a stance in which they are joined by Russia, China, and other nations), the border between these two countries has been relatively peaceful since the conclusion of the Kosovo War of 1998-99. The motivation for the Serbs to stir up unrest now can be nothing other than the inauguration of Donald Trump as the 45th President of the United States. Belgrade's strongest ally and patron has been Vladimir Putin of Russia, and no force contributed more to the independence of Kosovo than the NATO soldiers led by General Wesley Clark. Thus President Trump's affectionate talk about the former leader and musings about the obsolescence of the latter alliance are the simplest explanation for why the Serbs would feel that this was the opportune moment to be bold.
This all might blow over without producing so much as a footnote for future history books. But this could materialize into a crisis that sets the trajectory for the rest of Trump's term in office. We may find out in dramatic fashion just how much truth there is to the rumors that Donald Trump is a Russian lackey. If we don't achieve clarity on that question, we will at the very least be treated to our first test of the feasibility of Trump's reality-TV mode of communications. The Serbs will be listening very closely to every word said by Trump and his delegated spokespeople. If they get the sense that the Trump administration will not oppose an invasion, a forcible redrawing of the map may be attempted.
If that should happen, the long-term effects cannot be good. The extinguishing of Kosovan independence would be a restructuring much more radical than any of the recent Russian adventures in Georgia, Crimea, and eastern Ukraine, in that it would entail the dismantling of a territorial power that the US and its allies had recognized as sovereign. Allowing the Serbs to destroy such a significant geopolitical construct that so much NATO blood and treasure had been expended to effect will neuter the Alliance for good and all. Once that has happened, all of the boundaries of Eastern Europe and the Baltic States will be in play. Radicals will be incentivized to pursue dreams of "Greater Russia" at the expense of neighboring states, with war and chaos potentially being the final result.
Back in September I wrote that Donald Trump "disqualified himself by a number of statements he has made and
positions to which he has committed himself" which stood "in such stark breach of the political norms of our system," that he could not "reasonably fill the office of President." At the time I thought that the Baltic states, where Trump had expressed an unwillingness to foot the bill for our commitment to our NATO allies, would be the flashpoint where his words were likeliest to catch up to him. But the entire world has been listening closely to Donald Trump's "America First" rhetoric, and there are myriad local grievances and scores that aggressive actors will be tempted to settle if they get the sense that the US will stand aside. Unless Mr. Trump can gain in clarity and coherence quickly, we may be treated to an object lesson in the dangers of loose took very soon.
