In a forthcoming book titled "The Return of Great Powers," multiple former advisers of Donald Trump have expressed concerns that the former president would seek to formally withdraw the United States from the NATO alliance if he were to win a second term.

The book, set to be published on March 12, features insights from a former senior U.S. official who served in both the Trump and Biden administrations at a high level. According to the official, if Trump were to defeat President Joe Biden in the November elections, "the US will be out of NATO." This viewpoint was echoed by John Bolton, Trump's former national security adviser, who stated, "I think he would try to get out. NATO would be in real jeopardy."

The book also highlights Trump's disparagement of U.S. security commitments, extending to mutual defense agreements with South Korea and Japan. Retired General John Kelly, who served as White House chief of staff to Trump, revealed that Trump saw no value in NATO and was opposed to having troops stationed in South Korea and Japan, considering them deterrent forces.

According to Kelly, Trump believed that if the U.S. were not part of NATO, Russian President Vladimir Putin would not engage in aggressive actions. Trump had previously come close to withdrawing the U.S. from the alliance during his first term, as detailed in the book.

Trump's stance on NATO expenditure also drew attention. He had long complained about the unequal distribution of defense spending among NATO members, emphasizing that the U.S. paid more than other nations.

The former advisers warned that a second Trump term could result in the withdrawal of U.S. support for Ukraine and Taiwan as well, putting these countries at risk. Bolton cited Trump's comment from a 2023 Fox News town hall, where he claimed he could end the war in Ukraine in a day if reelected, implying that territorial concessions might be made for the sake of peace.

Concerns were also raised about Taiwan's vulnerability to a potential Chinese invasion. Bolton recounted how Trump visually illustrated the disparity in power between Taiwan and China by holding up a Sharpie pen tip and referring to Taiwan, while pointing to the Resolute Desk to represent China.

These revelations from former Trump advisers add to the ongoing debate surrounding U.S. foreign policy and the future of its alliances. As the book delves into the mindset of the former president, it provides valuable insights into his global strategy and potential implications for international relations.

It remains to be seen how Trump's potential withdrawal from NATO and the implications for Ukraine and Taiwan would be received by the international community, as well as by the American public. The upcoming book sheds light on this crucial aspect of Trump's presidency and its potential ramifications.
