Invoke the 25th Amendment or begin impeachment proceedings. This is not hyperbole — it is the only rational response to a president who posted a map of the US flag over Canada, Mexico, Greenland, Iceland, and Central America, invaded Venezuela to seize its oil, launched an illegal war on Iran without congressional authorization, and has now killed over 225 people by blowing up boats in international waters. As former Swedish Prime Minister Carl Bildt put it, if Xi Jinping posted a map claiming all of East Asia, "it would have been seen as either insane or dangerous — or both." The same standard applies here.
This isn't a policy disagreement. Trump's war with Iran has driven diesel to a record $5.88 a gallon, costing Americans $71.5 billion extra at the pump. Iran is now planning to escalate attacks on US bases. The Pentagon is polygraphing its own officers to suppress leaks. Every institution meant to check this president is being dismantled in real time. The midterms are less than two months away, but that is too long to wait. Use the constitutional tools available to you now.
