Trump administration is likely going to add further sanctions on Iran, specifically targeting their ballsistic missile development program.
Little doubt that Biden, a former member of the Cash on the Tarmac administration, which rewarded Iran for invading U.S. sovereign territory will do everything they can to roll it back. Which will immediately put the Biden administration (which will hopefully not be laced with Theocratic Dictatorship loving ghouls) at odds with Israel. Israel is working with the U.S. on crafting the sanctions against Iran's missile program.
