If the Biden administration's goal really was to prevent Iran from developing nuclear weapons, Biden and his advisors would have responded forcefully to Iran's actions. They would have strengthened the standing sanctions and imposed additional ones. But instead, Biden and Secretary of State Antony Blinken stopped enforcing key sanctions and so enriched and empowered Iran still further and awarded the ayatollahs for their brinksmanship.
In summary, both the content of the nuclear deal that Biden seeks to achieve and the administration's permissive responses to illicit Iranian nuclear and terror operations make clear that Biden's true object is to facilitate Iran's acquisition of nuclear weapons and hegemonic power, even at the expense of US allies, strategic interests and national security.
