Delivering the keynote address at the national memorial to the victims of Flight 93, who forced down their airplane hijacked by al-Qaida terrorists before it could be used as a weapon against the nation's capital, Bush warned of "violence that gathers within."
"There is little cultural overlap between violent extremists abroad and violent extremists at home," he said. "But in their disdain for pluralism, in their disregard for human life, in their determination to defile national symbols, they are children of the same foul spirit. And it is our continuing duty to confront them."
Bush's warning came barely eight months after the violent insurrection at the U.S. Capitol by supporters of then-President Donald Trump attempting to overturn the results of the 2020 election. It marked some of Bush's sharpest criticism of that attack and appeared to be an implicit criticism of Trump's brand of politics.
Bush lamented that "so much of our politics has become a naked appeal to anger, fear and resentment."
