With the clock ticking on President Donald Trump's May 12 deadline to either renegotiate or withdraw from the Iran nuclear deal, British Foreign Secretary Boris Johnson visited Washington Monday in a last-ditch bid to persuade him not to abandon the pact.
Britain is the third European power to lobby the White House in favor of saving the agreement, after Germany's Angela Merkel and French President Emmanuel Macron also tried to make the case.
Ahead of meetings with Secretary of State Mike Pompeo, Vice President Mike Pence and National Security Adviser John Bolton, Johnson warned that it would be "a mistake" to walk away from the deal.
"I am sure of one thing: every available alternative is worse."
"It has weaknesses, certainly, but I am convinced they can be remedied," he wrote in an opinion article for Monday's New York Times.
The 2015 deal, formally known as the Joint Comprehensive Plan of Action, offered Tehran billions of dollars in relief from sanctions in exchange for its agreement to curb its nuclear program.
Trump wants to ditch the Obama-era accord, saying that he will refuse to extend U.S. sanctions relief for Iran unless it is renegotiated; the deadline for sanctions renewal is Saturday.
Britain, France and Germany believe the deal is worth saving because it gets rid of 95 percent of Iran's enriched uranium and allows U.N. inspections with no advance notice.
"Now that these handcuffs are in place, I see no possible advantage in casting them aside," Johnson wrote. "At this delicate juncture, it would be a mistake to walk away from the nuclear agreement and remove the restraints that it places on Iran."
He added: "I believe that keeping the deal's constraints on Iran's nuclear program will also help counter Tehran's aggressive regional behavior. I am sure of one thing: every available alternative is worse. The wisest course would be to improve the handcuffs rather than break them."
Israel has long opposed the pact, saying it hasn't curbed Iran's wider aggression, such as its support for Hezbollah — a powerful Lebanese militia and political group — and its role in conflicts in Syria, Yemen, Iraq and Bahrain.
In his previous role as CIA director, Pompeo consistently portrayed Iran as the focus of evil in the Middle East and a worldwide threat. However, State Department official Brian Hook has been working on a compromise that would see the U.S. remain in the nuclear deal while extending its limitations to cover Iran's missiles.
Iran's President Hassan Rouhani said Sunday he would respond to any move to end the deal, and warned that the United States would regret such a decision to abandon the pact.
"America is making a mistake if it leaves the nuclear accord," he said.
