A former Thai senator has issued an open letter to the American public warning of a global leadership crisis and urging action to restrain the United States president, citing risks to international stability. On 19 March 2026, Dr Jemsak Pinthong posted the message on Facebook, addressing it to US citizens via the US Embassy in Thailand. He described the situation as an “international crisis with a pulse” that extends beyond domestic US politics.

The letter outlines concerns over what he characterises as erratic leadership behaviour, including proposals such as taking control of Greenland, issuing ultimatums to Cuba, threatening to invade Mexico and discussing the annexation of Canada. He argues these actions are not strategic but instead signal instability and declining leadership judgement. He states that such behaviour is “not normal” and reflects a leader overturning the system due to personal motives.
Dr Jemsak emphasises that while global citizens cannot vote in US elections, they are affected by the outcomes of US leadership decisions, particularly given the country’s nuclear capabilities. He asserts that statements such as “I didn’t vote for him” are insufficient at the international level, where consequences extend worldwide. He adds that responsibility ultimately lies with the American public, as part of the democratic system that produced the leadership.

The letter also raises concerns about the president’s age and mental state, describing him as nearing 80 and suggesting visible cognitive decline. It warns that a leader without long-term planning or perceived consequences could pose heightened risks, especially if driven by ego and a lack of restraint. Dr Jemsak questions why families across Asia, Europe, South America and Australia should face fears of war or economic crisis due to internal US issues.
Calling for immediate action, he urges Americans to use constitutional mechanisms to restrain and oversee the president, including potential removal if deemed mentally unfit. He stresses the urgency of acting before irreversible damage occurs, warning of the possibility of global conflict without a “reset button.” The message concludes by stating that the US must resolve the issue before it leads to wider global collapse.
Naewna the letter signals growing international concern over US leadership and its global impact, though no official response from US authorities or international bodies has been reported. It highlights the broader implications of domestic political decisions in major powers for global peace and security.
