It’s actually kind of amusing (sadly so) to see an Israeli talk about the dangers of Balkanization, and “manufactured” countries. Where was Israel before the 1940s?
Actually there is an important distinction: Israel exists by the exercise by its founders of the ancient ‘right of conquest’, something its founders exercised without apology, not having embraced the innovation of post-WW II international law of the inadmissibility of conquest. Moreover, the conquerors acted in their own self-interest. Isreal is not a ‘manufactured’ country, but one which arose a countries have all through history.
‘Kosovo’ as a country exists, on the contrary, due to the exercise of the old ‘right of conquest’ not by its founders, but by NATO, and the United States in particular, countries which have all formally signed on to the notion of the inadmissibility of conquest. In this sense it was ‘manufactured’, while Israel was not. Moreover, bizarrely, the conquerors in this instance, acted against their own self-interests.
