With due apologies to God, Voltaire and the Ukrainians, I must point out that if Ukraine did not exist, it would not be necessary to invent it.
It is not a great power, it has no resources the world cannot do without, and it is not a "vital strategic interest" to anybody except the Ukrainians. Not even to the Russians, although they are acting at the moment as though it were.
Bosnia was nobody's vital strategic interest either. It isn't now, and it wasn't 100 years ago. But Bismarck warned in 1898 that if there was ever another major war in Europe, it would come out of "some damned silly thing in the Balkans," and an assassination in Sarajevo in 1914 fulfilled his prophecy to the letter.
Some things have changed since then, however. The next world war will not come out of Ukraine no matter what happens in the next few weeks and months. Russia might invade Ukraine, there might even be a new Cold War for a while, but there will be no fighting in Europe beyond Ukraine's borders.
Apart from the Balkans there has been no full-scale war in Europe for the past 69 years, and there was never the slightest risk that the fighting in the 1990s would spread beyond the borders of former Yugoslavia. Indeed, there was probably never a single day during the 45 years of the Cold War when either side seriously considered attacking the other.
