How Much Further Will the US Go to Force Iran to Negotiate

Over the last few weeks, Iran has witnessed a series of unusual explosions at sensitive facilities like Natanz nuclear facility. Many analysts suspect sabotage by Israel or the United States. The United States did its best to make it hard or even impossible for Iran to benefit from the deal, even when it was part of the agreement. Since its withdrawal from the agreement in May 2018, the US doubled down on its efforts to ruin the deal and force Iran to negotiate a new deal, including its ballistic missile program and its regional influence. Now that the US maximum pressure has not delivered on its goals and there is not much time since the US Presidential election, how much further will the US go to ruin the nuclear deal and force Iran to negotiate How should Iran respond
