Because so many war plans simply do not survive the reality of war itself, each war is a unique universe unto its own and thus comparisons with previous wars, while useful, may also prove illusory. One of the many wrong assumptions about the Second Gulf War before it started was that it would somehow be like the First Gulf War, in which the pessimists had been humiliated by the ease of the victory. Indeed, the Second Gulf War unfolded in vastly different ways, this time proving the pessimists right. That is why the recent media refrain comparing a military operation in Syria with the one in Kosovo in 1999 worries me.
There are profound differences.
Syria has a population ten times the size of Kosovo's in 1999. Because everything in Syria is on a much vaster scale, deciding the outcome by military means could be that much harder.
Kosovo sustained violence and harsh repression at the hands of Serbian leader Slobodan Milosevic, which was met with a low-intensity separatist campaign by the Kosovo Liberation Army. Violence was widespread but not nearly on the scale of Syria's. Syria is in the midst of a full-fledged civil war. The toppling of Milosevic, moreover, carried much less risk of ever-expanding anarchy than does the toppling of Syrian ruler Bashar al Assad.
Kosovo was more or less contained within the southern Balkans, with relatively limited chance for a spillover -- as it turned out -- into neighboring countries and territories. Full-scale sectarian anarchy in Syria threatens to destabilize a wider region.
The Kosovo Liberation Army may have been a nasty bunch by some accounts, with criminal elements. But it was not a threat to the United States like the transnational jihadists currently operating in Syria. For President Bill Clinton to risk bringing to power the Kosovo Liberation Army was far less of a concern than President Barack Obama possibly helping to midwife to power a Sunni jihadist regime.
Kosovo did not have a complex of chemical weapons facilities scattered throughout its territory as Syria does, with all the military and logistical headaches of trying to neutralize them.
The Kosovo war campaign did not have to countenance a strong and feisty Russia, which at the time was reeling from Boris Yeltsin's incompetent, anarchic rule. Vladimir Putin, who has significant equities in al Assad's Syria, may do everything in his power to undermine a U.S. attack. Though, it must be said, Putin's options should Obama opt for a significant military campaign are limited within Syria itself. But Putin can move closer to Iran by leaving the sanctions regime, and ratchet-up Russia's anti-American diplomacy worldwide more effectively than Yeltsin ever wanted to, or was capable of.
The Kosovo war did not engage Iran as this war must. For all of the missiles that America can fire, it does not have operatives on the ground like Iran has. Neither will the United States necessarily have the patience and fortitude to prosecute a lengthy and covert ground-level operation as Iran might for years to come, and already has. A weakened or toppled al Assad is bad for Iran, surely, but it does not altogether signal that America will therefore receive a good result from this war. A wounded Iran might race even faster toward a nuclear option. It is a calculated risk.
The Kosovo war inflicted significant pain on Serbian civilians through airstrikes, but the Syrian population has already been pummeled by a brutal war for two years now, and so it is problematic whether airstrikes in this case can inflict that much more psychological pain on the parts of the population either still loyal or indifferent to the regime.
