If the US is preparing for major hostilities with Iran again, one of the indicators from my & @MATA_osint perspective would be the evacuation of tanker aircraft from Al-Udeid Airbase in Qatar again...

At least some tankers appear to be moving to Israel this morning and last night, although not "en-masse" as such

The observation points to potential US force posture changes and could be an early signal of escalation in the region.
