In a joint press conference in London, President Trump and Prime Minister May emphasized the cooperation between their two countries in the security field and announced that they will not allow Iran to develop nuclear weapons.

President Trump stated: “Among the pressing threats facing our nations is the development and spread of nuclear weapons, perhaps that's our biggest threat."

He continued: "The United States and the United Kingdom are determined to ensure that Iran never develops nuclear weapons and stops supporting and engaging in terrorism, and I believe that will happen."

Regarding NATO, both leaders expressed their expectation from other members to contribute more: "We expect a growing number of nations to meet the minimum 2 percent of GDP requirement. To address today's challenges, all members of the alliance must fulfill their obligations. They have no choice," said President Trump.

Hours earlier, President Trump supported U.K leaving the EU in a tweet, saying: “Big Trade Deal is possible once the U.K. gets rid of the shackles.”

Prime Minister May also stated that her country, along with the U.S, will not allow any threats against the security of the two countries or their allies.

Regarding the disagreement between the two countries over the JCPOA, Prime Minister May stated: “Although we wish to remain in the nuclear deal with Iran, our goal is the same as the United States in this matter.”

She asked Tehran to comply with its commitments and “Britain will try to deescalate the tension, because it is not in the interest of anyone.”
