We are at war. The United States guided an ATACMS missile into Russian territory yesterday. Imagine the absurdity of if China put missiles on the Mexican border and guided them into missile storage facilities 186 miles inside the border.
Who is now threatening nuclear war?
Imagine the US engaging in an invasion of Mexico as equally stupid and unprovoked as Putin's invasion of Ukraine. Then not only would Mexico have a perfect right to seek whatever help it needed to resist the aggression directed at it, we would -- unless we were damned fools -- fully expect Mexico to seek and obtain that help.
