A bipartisan group of 140 House lawmakers is urging the Biden administration to take a comprehensive approach to threats posed by Iran beyond just reviving the 2015 nuclear deal.

As the Biden administration considers negotiations with Iran, we write to express our bipartisan and shared view that we must seek an agreement or set of agreements with Iran that are comprehensive in nature to address the full range of threats that Iran poses to the region, the lawmakers wrote in a letter Tuesday to Secretary of State Antony BlinkenAntony BlinkenJill Biden: Global pandemic underscores how ‘we are all connected’Seoul sees hope in Biden’s North Korea approachUS proposes interim power-sharing deal between Taliban, Afghan government: reportMORE.

As Democrats and Republicans from across the political spectrum, we are united in preventing an Iranian nuclear weapon and addressing the wide range of illicit Iranian behavior, they added.

It comes as the Biden administration has expressed a willingness to talk with Iran about rejoining the nuclear pact between Tehran and several world powers that was negotiated by the Obama administration.

Tuesdays bipartisan letter comes after one from 150 Democrats in December urging Biden to swiftly re-enter the Iran nuclear deal and one from 120 Republicans in February warning Biden not to rejoin the nuclear deal without significant changes.

Some of the same lawmakers signed both Tuesdays bipartisan letter and one of the partisan letters.

Tuesdays letter acknowledged that differences of opinion continue to exist about what the parameters of a final deal should entail and the process by which it is reached, but it said there is a bipartisan consensus on several issues.

Three core tenets – their nuclear program, their ballistic missile program, and their funding of terrorism – must be addressed from the outset, the lawmakers wrote.

While the Biden administration has expressed concern about other Iranian activities, including support for proxy forces in the region and its ballistic missile program, it has argued the nuclear program is the top threat that should be addressed first.

Once the existing nuclear deal is secured, Biden has said he would seek a “longer and stronger” deal that further tightens nuclear constraints and addresses Irans other concerning behavior.

There is consensus within Congress that allowing one of the worlds leading state sponsors of terrorism to obtain nuclear weapons is an unacceptable risk, the lawmakers wrote in their letter. We recognize that there is not a singular diplomatic path forward on these objectives and we look forward to working with you as partners to achieve lasting peace in the region.
