Are you comparing 8 years of bloody war on the ground where chemical weapons were used extensively by the Iraqi forces to 39 days of air strikes?
Adjusted for inflation, the war with Iraq cost Iran about 2 trillion dollars in 8 years. That's about $250 billion per annum. The US-Israel attacks on Iran have already cost Iran over $500 billion in a matter of 51 days. That's almost $10 billion per day.
Also, back in 1980, Iran was the world's 12th or 13th largest economy by nominal GDP. Where is Iran now? 51st, and going down fast. Even behind countries like Pakistan, Nigeria, Vietnam, Thailand, Philippines, Egypt, Chile, Romania, etc.
