War damage exceeds pre-war GDP by more than six times
The World Bank's 2022 assessment put the cost of destruction at $400B+. Syria's entire economy before the war was roughly $60B per year. Even if every dollar pledged in international aid since 2012 were fully delivered — $30B total — it would cover less than 8% of the damage.
