It’s important to understand that the JCPOA is not just an agreement between the US and Iran, but one negotiated alongside our partners in the P5+1 – the UK, France, China, Russia and Germany – and endorsed by the United Nations security council. Trump’s withdrawal further deepens tensions with our most important democratic allies, France, the UK and Germany, who all continue to support the agreement and have consistently said that it is in their own national security interests to see it upheld.
Trump also rejected the advice of his own top national security officials like the joint chiefs chairman, Gen Joseph Dunford, and defense secretary, James Mattis, both of whom have repeatedly stated that staying in the agreement is in the national security interests of the US. Nuclear non-proliferation and national security professionals around the world share that assessment. Just as he has done on the issue of climate change with his withdrawal from the Paris climate accord, Trump has chosen to ignore the overwhelming expert consensus and sided instead with a small ideological faction, with disastrous consequences for our global security.
