Ever since the beginning of the 20th century, the United States and Great Britain have had a “special” relationship and friendship, and became allies in 1917 when the US went into World War I.
Theodore Roosevelt was very close to Great Britain in the first decade of the 20th century, and Woodrow Wilson was a known “Anglophile” in his writings and scholarship during his years as a professor and university president before he ran for public office.
While the alliance during World War I did not survive in the 1920s and 1930s isolationist period, we were still friendly toward our former mother country.
Then in World War II, Franklin D. Roosevelt and Winston Churchill became great allies and friends, as both nations fought against Nazi Germany, Fascist Italy, and Imperial Japan.
After World War II, the United States became the leader of the free world democracies, and allies in the North Atlantic Treaty Organization, and the British fought in the Korean War, the Gulf War, and in the War on Terror after September 11 in Iraq and Afghanistan.
While the British did not send troops into the Vietnam War, they have always been perceived as our closest friends in the world, alongside Canada.
But now, Donald Trump has openly criticized the British government and its leader Theresa May, and Trump is the most unpopular American President ever in modern times by every measure.
This is a very sad situation, and it is clear that we have just witnessed the destruction of this special friendship, relationship, and alliance between the US and Great Britain.
Trump even had some missteps while meeting Queen Elizabeth II.
