This is bad news for Americans and democratic allies, as a Pulitzer Prize-winning historian warns that the US is sliding from liberal democracy toward one-party rule.

• Democracies today rarely die by coup but by elected leaders slowly taking apart courts, civil service, and media, as happened in Hungary under Orban.
• Trump's net worth jumped from $2.3 billion to $6.5 billion in office, with the Saudis investing $2 billion in Jared Kushner's fund — a level of presidential business conflict never seen before in the US.
• ICE has become a new national paramilitary force, the Justice Department is being used to go after Trump's enemies, and tech CEOs who once attacked Trump now stay silent to protect their businesses.
• Global allies are hedging after Trump threatened to invade Greenland — Canada, the EU, India, and Japan are building new trade and security ties that bypass the US.
• The Iran strikes were poorly planned because nobody around Trump dares to push back, and his approval ratings are now at record lows even among former supporters like Tucker Carlson.

Outlook: American democracy will keep declining toward a one-party system, and even after Trump leaves, many broken norms and global alliances will not return to normal.
