Who Is Boris Johnson? Trump-Defending, US-Fan Faces Big Battles as He Takes Charge of Britain

Britain has a new Prime Minister. Britain's Conservative Party has chosen Boris Johnson.

He's a fan of America and has defended President Trump. He's also vowed to make Brexit happen in three months, but his first challenge will be the escalating naval crisis with Iran.

Boris Johnson arrives at number 10 Downing Street at a challenging time for any prime minister, with fears that war could break out with Iran.

Iran's Revolutionary Guards seized a British-flagged oil tanker in the Strait of Hormuz last Friday in revenge for the British seizure of an Iranian tanker off Gibraltar earlier this month.

But Johnson has already signaled he's no hawk on Iran. During last week's TV debates, Johnson said he would not support US military action against Iran.

And in 2018, when he was foreign minister, Johnson traveled to Washington to try to persuade President Trump to stay in the Iran nuclear deal, saying the British government remained committed to the deal.

As for his pledge to leave the European Union by October 31 no matter what, Johnson inherits the same divided Conservative Party and Parliament that helped stymie and finally bring down Prime Minister Theresa May.

Johnson may also be handed a 'no-confidence vote' and early election within weeks.

But he does have a friend across the Atlantic.

President Trump said, "I like him. I like Boris Johnson. I spoke to him yesterday. I think he's going to do a great job. I think we're going to have a great relationship."
