To prohibit the United States from rejoining the Joint Comprehensive Plan of Action (JCPOA) until the President makes certain certifications, and for other purposes.

Bill 117 HR 3966, also known as the "Preventing Iran Nuclear Deal Act," aims to prevent the United States from rejoining the Joint Comprehensive Plan of Action (JCPOA) until certain conditions are met. The JCPOA, also known as the Iran nuclear deal, was an agreement reached in 2015 between Iran and several world powers, including the United States, aimed at limiting Iran's nuclear program in exchange for sanctions relief.

The bill requires the President to make several certifications before the United States can rejoin the JCPOA. These certifications include ensuring that Iran has fully complied with all of its obligations under the agreement, that Iran has ceased its support for terrorism, and that Iran has released all American citizens held in captivity.

Additionally, the bill prohibits the use of federal funds to support the reentry of the United States into the JCPOA until these certifications are made. This means that the President must meet these conditions before any taxpayer money can be used to support the agreement. Overall, Bill 117 HR 3966 seeks to ensure that the United States does not rejoin the JCPOA without certain assurances from Iran and aims to hold Iran accountable for its actions before any further engagement with the agreement.
