A rundown of the outside and inside forces that could be pulling America apart, framed as a warning that the real threat may be at home.

• The list of outside rivals spans economic ones like China and India, and governments run on very different systems — Iran, China, and Russia.
• Other threats named are religious extremism, the tech race with China, South Korea, Taiwan, and India, and foreign governments trying to sway US decisions.
• The bigger worry is internal: schools shaping kids, the cost of living, falling birth rates, and the breakdown of the traditional family.
• Falling trust in government and media, plus people stoking division for fame or their own gain, round out the danger list.

Outlook: Expect the argument to build toward the idea that America's deepest divisions come from within, not from foreign enemies.
