My hope is that with Biden, the sanctions will lift off and once the oil can officially be sold again, money will poor in the country. In addition, when/if the US comes back in the JCPOA, most European countries can come back and continue their previously made business deals with Iran. That in itself will create more jobs at the same time that people can breath a bit.
Having said that, my worry is Biden's age. He's already 77 years old. If he survives 4 years, he'd be 81. I doubt he will continue his reign as president even if he wanted to. and looking at recent history, republicans have always replaced democrats consecutively in the white house. So the next republican president may go back on Trump's foot steps again.
Anyways, first thing first......let's hope Biden wins.
