Former US President Barack Obama sharply criticized Trump's decision to abandon the 2015 Iran deal.
"There are few issues more important to the security of the United States than the potential spread of nuclear weapons, or the potential for even more destructive war in the Middle East. That’s why the United States negotiated the Joint Comprehensive Plan of Action (JCPOA) in the first place," wrote Obama on Facebook.
"That is why today’s announcement is so misguided. Walking away from the JCPOA turns our back on America’s closest allies, and an agreement that our country’s leading diplomats, scientists, and intelligence professionals negotiated."
