What is the US strategy to prevent Iran from obtaining nuclear weapons?

The US has reinstated a maximum pressure campaign aimed at preventing Iran from acquiring nuclear weapons. This strategy, implemented under President Donald Trump, specifically targets Iran's oil exports with the goal of reducing them to zero, thereby economically pressuring the country to abandon its nuclear ambitions. Recently, US Secretary of State Marco Rubio and Israeli Prime Minister Netanyahu have made comments reinforcing this stance, demonstrating a unified US-Israeli position on the issue. Iran has responded by dismissing these threats, with an Iranian Foreign Ministry spokesperson stating they 'cannot do a damn thing to Iran.'
