Ask Putin why Ukraine seems not to be incredibly unimportant. As he invaded Ukraine. Putin's behavior contradicts with your statement. Although you seem to be a Putin fan. " So the question is, why does the world care about Ukraine?" Because the Russians signed in 1994 an agreement that they would respect Ukraine's territory. And they would not interfere in Ukraine's politics. Like always they never respect any laws or even agreements they signed themselves. The document is attached below. We also do care about Ukraine as Russia is an aggressive country that wants to control other nations with violence and terror. That should be stopped completelly. The entire East European area escaped from Russia when they collapsed, and they all hate the Russians. Russia is also using a genocide to control Ukraine. They have no respect at all for innocent civilian lifes and are having fun killing them. Bombing a hospital, and mater taking people as living shields in a hospital in Mariupol is just one example.
