The tens of billions of dollars Iran invests into fighting Israel are (in my opinion) much better spent investing into developing the Iranian people and economy. Spending billions of dollars funding proxy wars, fighting a pointless forever war against Israel, pursuing nuclear weapons, and firing drones and missiles at your neighbors is a foolish foreign policy. Iran is asking for trouble.
If Iran had a different foreign policy, this current conflict would never have happened. Iran's situation was entirely avoidable.
