"We must do something, this is something" reasoning is incredibly dangerous when the only perceived options are reaching for bigger and bigger hammers (bombs).
Another US official noted that when the military plans, it develops a menu of options for policymakers that range from the high-end to low-end. Higher-end targets, including those that are located deep underground, require bigger bombs, and the MOAB is the biggest, the official added.

But there are questions around whether the MOAB would be an effective munition to use against Iran’s nuclear facilities and other sites that are located deep underground. While the GPS-guided bomb is capable of destroying an area equivalent to nine city blocks, it likely lacks the capability to penetrate deep enough under the surface to destroy the suspected nuclear facilities at Pickaxe, which is believed to be fortified by layers of granite, and other remaining Iranian nuclear sites, sources said.
You can blow up stuff and kill people, but Iran is a very big country. Hell, most countries, even small ones, are very big countries relative to the scale of damage that non-nuclear missiles and bombs can do.
But we must do something! Dropping a big bomb is something!
Likely Van Jones will get on TV and inform us, after dropping some MOABs, that, once again, Donald Trump has become president on this day.
