( CNN) What should we make of President Trump's offerthis week to meet with Iran's leaders without preconditions? Five hundred days into the chaotic Trump presidency , not much.

He is the first president in American history who cannot define the national interest untethered to his own personal vanity, political needs and obsession to dominate every tale. This isn't foreign policy; it's a soap opera.

Indeed, without a broader policy toward Iran, which this administration does not have, there is far less going on here than gratifies the eye.
