British Foreign Secretary Boris Johnson, who has scheduled talks with US officials in Washington this week, said Sunday that the UK and its partners are united in tackling Iran’s behavior in the Middle East The UK, the United States, and European partners are "united in our effort to tackle the kind of Iranian behavior that makes the Middle East region less secure - its cyber activities, its support for groups like ‘Hezbollah’, and its dangerous missile program, which is arming Houthi militias in Yemen," Johnson said in a statement. He is scheduled to meet with US Vice President Mike Pence and national security adviser John Bolton, for talks on Iran, North Korea, Syria and other issues, Britain said. His trip follows visits in recent weeks by the leaders of France and Germany, who tried to convince US President Donald Trump to stick with the Iran nuclear deal. All three European countries signed the 2015 agreement, along with Russia and China. In an op-ed Sunday for The New York Times, Johnson wrote that the agreement offered the fewest disadvantages of all the options available. "It has weaknesses, certainly, but I am convinced they can be remedied. Indeed at this moment Britain is working alongside the Trump administration and our French and German allies to ensure that they are," he wrote. Trump is set to decide by May 12 whether to withdraw from the deal, in which Iran agreed to curb its nuclear program in exchange for sanctions relief.
