Sounds like justification for a false flag operation by the US government. How would they transport these massive things and launch them on a different continent? That, or the US is trying to justify that this illegal war is on their doorstep and need to expand their terror.

"Reichstag fire" attempts are definitively a legitimate concern. But as Ukraine has demonstrated, all you need to get a drone army deep into a country attacking you is a regular shipping container.

The drones Iran are using are actually relatively small, you can fit 5 of them into a medium sized truck and they can launch in-situ, which is how they've been using them in ground operations. Doesn't seem that much of a stretch to put a bunch of them into shipping containers.
