Which empire lasts longer without breaking — the United States or China? The first pass said sixty-forty to America; this one runs the same ledgers through the sources the other side trusts — Tehran, Beijing and Moscow, Mearsheimer, Sachs, the dissident press — and the verdict moves closer to even: Iran a confirmed strategic defeat, Ukraine a probable loss, the dollar's weaponization feeding its own erosion, and a China-collapse narrative with thirty years of failed predictions behind it. The honest answer is a coin flip, with the largest outcome neither empire breaking first — both eroding while the multipolar middle collects.
