Woody Johnson, US ambassador to the United Kingdom, is warning Britain to support President Trump’s stance on the Iran deal. The ambassador claims that failure to do so will have grave trade consequences between the United States and Britain.

To date, Britain is allied with its European partners, who wish to alleviate sanctions on Iran in exchange for 97% of the country’s Uranium. The cutting down of uranium resources was meant to leave Iran incapable of pursuing Tehran’s military nuclear ambitions.

Just last week, Britain, France, and Germany released a joint statement declaring the Iran deal is delivering positive results. Federica Mogherini, High Representative of the EU for Foreign Affairs also expressed her support, “The deal is working, as certified eleven times by the International Atomic Energy Agency, and it is strategic for our security.” Yet not many seem to agree.

Among those opposed, is Woody Johnson. The Ambassador is urging Britain to join President Trump in withdrawing support of the Joint Comprehensive Plan of Action and enforcing stricter sanctions upon Iran given their involvement in “transnational criminal activity.” The ambassador justified his stance on the UK Sunday’s Telegraph, urging Britain to “move on” from the “flawed” 2015 Iran deal.

According to Johnson’s article in The Telegraph, the Iranian regime has anything but stopped its development of nuclear weapons since the Joint Comprehensive Plan of Action. “And in light of its destructive choices, it should be all the more concerning that the Iran deal did not even put a permanent block on its ability to develop nuclear weapons,” wrote Johnson.

In his article, Johnson also shows concern for the Iranian people as well, as he explains how the public’s income is being redirected towards nuclear development. The US Ambassador stresses “The Iranian people deserve better…They need a government that pays workers, not terrorists.” The politician strains that stronger sanctions would not only protect Iranians but US allies across the globe as well.

Critics of the Iran deal believe that the broad lifting of sanctions and embargoes from the European Union and allies will help Iran heighten its influence in the region. In one of his tweets, Trump supported this stance saying, “It does nothing but make Iran rich and will lead to catastrophe.”

Last week, the United States reinforced its strict sanctions on Iran. President Trump warned that any nation or business who forfeited universal good will to engage in business with Iran will suffer serious trade consequences with the United States.

No statement has been issued by Britain in response to Johnson’s article on The Sunday Telegraph. Only time will tell if Johnson’s plea has swayed the nation’s view on the matter.
