'Everyone hopes President Biden will step down gracefully and simply resign the presidency. But what if he doesn't? A hypothetical may help explain what could happen.
Communist China has sought the return of Taiwan to the mainland's control since 1948. In the last 15 years, mainland China has had a vast naval build-up that presents a major threat to the U.S Pacific Fleet. China has observed that President Biden has signs of dementia. It is also aware of the provisions of Section 4 of the 25th Amendment, and the cumbersome process of transferring power from the president to the vice president in the event of disability. The leaders of China conclude that a swift attack on Taiwan would cause chaos in the Biden White House command structure that would not be resolved for several days. By the time the U.S. responded militarily, China would have an insurmountable advantage in the invasion that could not be undone with conventional weapons. China also concludes that the U.S. will not use nuclear weapons to defend Taiwan.
On July 23, 2021, the 100-year anniversary of the founding of the Chinese Communist Party, China launches a massive invasion of Taiwan. As news is related to President Biden, he is overwhelmed and shuts down mentally. An order is signed by President Biden authorizing the U.S. Pacific Fleet to respond to the threat. However, the military chain of command wants to meet with the president to verify that he has signed the order and that he Is mentally competent. Members of the Joint Chiefs meet with the president and determine that he is not mentally competent and refuse to obey the order.
On July 24, Kamala Harris calls an emergency Cabinet meeting to invoke the provisions of Section 4 of the 25th Amendment and to remove the president from office. A majority of the Cabinet declares that it will not decide until it sees medical proof of disability. President Biden refuses to consent to a medical exam.
July 26, at another emergency Cabinet meeting, affidavits and witnesses are presented demonstrating President Biden's inability to govern. The majority of Cabinet members vote in favor of removing President Biden, and a written declaration is submitted to both houses of Congress. Upon delivery, Kamala Harris becomes acting president. Two hours later, President Biden delivers a written declaration to both houses of Congress that he has no inability to govern and resumes being president.
July 27, V.P. Harris and a majority of the Cabinet submit a second written declaration to both houses of Congress that again states that President Biden is unable to discharge the powers and duties of his office. Upon delivery, V.P. Harris again becomes acting president. Congress must schedule the trial within 21 days of July 27. A trial is scheduled for August 16.
July 28, Acting President Harris gives an order to the Pacific Fleet to provide logistical support to the Taiwanese military. The military responds that it will take at least five days for a carrier group to arrive in the area, which will be too late to offer assistance to the Taiwanese.
August 3, Taiwan announces its unconditional surrender to China, and major hostilities cease.
August 16, over two-thirds of both the Senate and the House vote that President Biden is unable to discharge the powers and duties of his office, and V.P. Harris shall continue as acting president.'
