Maybe, but they were not building it before the sanctions. Now I wonder if this disaster will be the main plea for lifting the sanctions, "millions will die in the next week!" or something similar to what was happening with pro-Palestinian propaganda. Come to think of it I wonder if the recent burst of news from Iran is just an attempt to lift sanctions and there is no severe draught... Just something common to happen from time to time.
They were building and investing in all sorts of infrastructure. And they still are at a slower and expensive pace. Obviously you are a Zionist supporting the downfall of Iran. Otherwise you would not have referred to pro Palestine propaganda
