The Signal chat leaks are the story of the week. While the media argues over government communications security protocols, the precise definition of “war plans,” and whether Mike Waltz or Pete Hegseth should be the fall guy, many Americans are left with a much more important question: who, what, and why are we fighting in Yemen? The U.S. has 750 military bases across 80 countries, and just a couple of months into the return of “America First” to the White House, we’re already back to launching attacks in Yemen—without a formal declaration of war or even congressional debate. From George Washington’s warnings against foreign entanglements to Ron Paul’s modern anti-interventionism, we’ve been wrestling with this issue for a long time.
