U.S. President Donald Trump and his wife Melania Trump recently attended the North Atlantic Treaty Organization (NATO) Alliance’s 70th anniversary at the Buckingham Palace. Queen Elizabeth, Secretary-General of North Atlantic Treaty Organization Jens Stoltenberg, Prince Charles, and Camilla, Duchess of Cornwall, welcomed the couple as they arrived.

The royals shook hands with Donald and Melania Trump. But eagle-eyed fans noticed that it seemed like Prince Charles was giving the 45th and current president of the United States the middle finger.

Although Prince Charles was just clearly scratching his nose, many wondered why he had to use his middle finger to do that in front of Donald Trump. “As Trump is annoying the Queen, is Prince Charles really needing to use his middle finger to scratch an itch that just can’t wait, or is he flipping the bird to Trump? Just asking” one wrote.

Donald Trump can be considered as one of the most popular US Presidents of all time. However, his popularity is not because of how people like his leadership, but because the majority do not agree with his views.

With that said, anti-Trumps are more than pleased to see that Prince Charles seemed to be giving the US President the middle finger. “Prince Charles flipping the bird at Donald Trump has united people across the Atlantic more than 70 years of Nato summits ever has,” one posted. “He did me a favor!!!!” another one commented. Some netizens added, “Long live the future KING!!!!!” “That was so intentional. A tip of the hat to the future king,” and “Using Dinky Donnie’s own signature move against him?”

One royal fan even shared his newfound respect for Prince Charles for the alleged middle finger moment. “Well good golly, something to admire about an otherwise useless royal,” he said.

Meanwhile, Prince Charles is the firstborn of Queen Elizabeth and Prince Philip and he will be taking over as the King of England once Her Majesty retires. Royal expert Richard Betherlson claims that the Prince of Wales "fundamentally running the Royal Family" for years, so it would be an easy decision for the Queen to allow her son to take full control of the monarchy sooner than expected.

"I myself felt that, after the Duke of Edinburgh retired at 95, it set the way and was a bit of a trial balloon for the Queen to follow suit in a few years,” he said. “She’s about two years away from that now, the Duke of Edinburgh is 98.”
