The United States conducts the largest logistical transfer operation in its history:

This 30-second video shows U.S. airlift supply activity in West Asia over just the past seven days (sped up 20,000 times).

This type of around-the-clock activity indicates the largest airlift operation in the history of the U.S. military, surpassing even the 2003 Iraq War operation.

The volume of this cargo transport far exceeds the scope of a simple resupply operation; all strategic U.S. warehouses in the region are almost fully utilized, and work is underway to raise them to maximum capacity.

Billions of dollars are not wasted on hollow threats or show maneuvers.

All of this points to military preparations ahead of a paralyzing preemptive strike, and perhaps to support the launch of a ground operation.
