The US has reimposed Iran’s oil sanctions. What does that mean for Tehran?

The US has reimposed stringent oil sanctions on Iran, reversing a temporary waiver that had lifted penalties on foreign investors buying Iranian oil. This move is a significant setback for Tehran, which had been banking on an economic boost after years of sanctions. The sanctions could severely impact Iran’s economy, especially its oil revenue, which is crucial for its financial stability and international relations. This decision could also complicate any future negotiations or agreements regarding Iran's nuclear program.
