The US must have several dozen spy satellites pointed at Iran. We get various imagery to show us successful strikes. Where are the images of the mass slaughter in the street?
The number I keep seeing is 30k killed. That's not an easy endeavor over the course of a week without big logistical hurdles. The trucks, the digging equipment, the furnaces to burn the bodies, all should have some visible trace that the US gov could point to as proof.
Yet all we got is a "trust me bro".
