"America is more isolated, less respected, weaker at home, and ultimately less safe under President Trump’s leadership. Whether it is Trump’s immoral, unwise, and botched travel ban on Muslim-majority nations; his reckless Twitter warmongering on North Korea; or his self-isolating moves to upend the Iran nuclear deal and risk another military confrontation in the Middle East, the result has been the same: America is appreciably less secure than it was a year ago. And the Trump administration’s daily campaign against the nation’s diplomats, intelligence community, law enforcement, and civil servants is gutting the very national security apparatus that the president will need to confront threats to America. Unfortunately, the damage that President Trump has done to the United States’ reputation and interests around the world will also have long-term consequences for Americans. Fewer nations will want to work with us, fewer will trust our word, and still fewer will want to fight alongside us if and when the time comes. Nations will look elsewhere for leadership, including to China, further jeopardizing the international rules that America and its democratic partners have defined since World War II to favor freedom and prosperity."
