The President tells the UK he does not need their aircraft carriers because the war is already won.

The Prime Minister of the United Kingdom, on Saturday, through the Ministry of Defence, announced that the HMS Prince of Wales, one of the Royal Navy’s two flagship aircraft carriers, had been placed on high readiness in connection with the ongoing American campaign in Iran. The announcement, by the standard of these matters, was a gesture of allied solidarity. It was, in the official sense, a non-trivial commitment. The Prince of Wales is a sixty-five-thousand-ton vessel with a crew complement of fifteen hundred, and the United Kingdom maintains exactly two such ships.

The President of the United States, on Sunday, on his social media platform, declined the offer. The post, in its entirety, included the phrase, “we don’t need them any longer,” the phrase, “But we will remember,” and the phrase, “We don’t need people that join Wars after we’ve already won!”

The chronology, by the standard of allied relations, is the part to mark. The British government, by the date of the President’s post, had been an active participant in the operation for nine days. The United Kingdom had, on the first day of the campaign, approved the use of British bases at Diego Garcia and Akrotiri for the launch of American sorties. The Royal Air Force had been flying refueling and intelligence missions over the Persian Gulf since February 28. The Royal Navy had a destroyer in the Strait of Hormuz already.

The phrase “people that join Wars after we’ve already won” is, in the documentary record of the past nine days, not factually defensible. The British were there from the first hour. The British were there on the day of the post. The post says the British are showing up late.

The Prime Minister, asked about the post on Sunday afternoon, declined to comment beyond a statement that confirmed the UK’s continuing support for the joint operation. The Foreign Secretary, asked about the post on Monday morning, gave a similar answer. The British press, asked about the post for the rest of the week, did not give a similar answer. The Times, the Guardian, the Telegraph, and the Mail all ran lead-page stories. The headlines included variants of the words “snub,” “insult,” and “ungrateful.”

The President, on Monday, did not delete the post.

It is worth noting the operational consequence. The Prince of Wales, in the days after the post, did not deploy. The Ministry of Defence, in subsequent statements, did not commit it. The American request to NATO partners later in the month for help securing the Strait of Hormuz, the request that came after Iran closed the Strait, will not be answered, in any meaningful operational sense, by the United Kingdom. The reason given to Downing Street by its own backbenches will be the post.

A serious country, in a serious moment, would have accepted the carrier and sent a thank-you note. A less serious country would do what was done: post that the ally was late, on the platform, in the morning, and let the carrier stay home.

Calmly documenting the decline.
