I didn't talk about attack/bombing the country I was talking about taking a part of that country by force. Countries that didn't recognized Kosovo are the countries that have similar issues, like Spain for example. Turkey and Greece have issues between them over the Cyprus and that the reason why Greece didn't recognized it, and the fact that they are both Orthodox Christians, and Turkey recognized it because Kosovo has mainly Muslim population.
Spain supported the bombing campaign verbally, although they didn't participated in it physically. Greece, on the other hand opposed the bombing. And dozens of Greek volunteers served in Kosovo on the Serbian side (alongside volunteers from Russia, Bulgaria, Georgia and Armenia).
