The war ended with Croatian victory, as it achieved the goals it had declared at the beginning of the war: independence and preservation of its borders. Approximately 21–25% of Croatia's economy was ruined, with an estimated US$37 billion in damaged infrastructure, lost output, and refugee-related costs. Over 20,000 people were killed in the war, and refugees were displaced on both sides. The Serb and Croatian governments began to progressively cooperate with each other but tensions remain, in part due to verdicts by the International Criminal Tribunal for the former Yugoslavia (ICTY) and lawsuits filed by each country against the other.
