When President Trump retweeted several anti-Muslim videos last month, Britain's Prime Minister Theresa May was quick to lecture the U.S. president.

May delivered a rare public admonishment of an American president, declaring that Trump was "wrong" to share the videos, which she said were posted online by a "hateful" British far-right group, Britain First.

"I'm very clear that retweeting from Britain First was the wrong thing to do. Britain First is a hateful organization. It seeks to spread mistrust and division in our communities. It stands against common British decency," she said on November 30 while in Amman, Jordan.

Trump's posts included videos titled "Muslim Destroys a Statue of Virgin Mary!" and "Muslim migrant beats up Dutch boy on crutches!"

But Trump, as he often does, fired back — and he didn't mince words with the leader of America's longtime ally.

So fast forward a week — actually, less than a week. A terror plot to assassinate May — a plot, it might be noted, hatched by Islamic terrorists — was foiled by British authorities, British papers reported.

Naa'imur Zakariyah Rahman, 20, from north London, and Mohammed Aqib Imran, 21, from southeast Birmingham, were arrested. The Metropolitan police said they had been charged “with the intention of committing acts of terrorism” and with “engaging in conduct in preparation for giving effect to that intention," The Guardian reported.

"Security officials believe they have thwarted an alleged plot to assassinate Theresa May by terrorists who would first bomb their way into Downing Street and then kill the prime minister, it has emerged," said The Guardian.

In court proceedings, prosecutor Mark Carroll told the court that Rahman planned to detonate an improvised explosive device at the gates of 10 Downing Street, where May lives, then storm her office and kill her.

"The secondary attack was to be carried out with a suicide vest, pepper spray and a knife," he told the court.

Rahman, as it turns out, was carrying two explosive devices when he was arrested last week. "His purpose was to attack, kill and cause explosions," Carroll said.

Oh, the irony.
