This is somewhat of an exaggeration... the US has plenty of cargo planes that can land on a carrier and enough local airfields nearby for a quick stop to refuel ...
But this requires a thoroughly set up plan for logistics and that's where the higher ups don't see the need (nor for making a plan of action in this war in the first place, they just raced out the door shooting wildly)...
The problem lies in the complete bubble the higher ups are living in, hegseth has access to unlimited food and drink and is the exact type to waive complaints away by uttering a statement in the vein of "let them eat cake".
Most of the other staff left over by now at the Pentagon are bootlickers and yes men who live in the same bubble of awesomeness, too afraid to fall out of it.
Same with trump, surrounded by yes men afraid of telling him otherwise, because anyone who does will be punished, so trump is fully enveloped in the same bubble of awesome and thinks everything he says or thinks up is the best tasting shit ever...
It's kinda weird how the US is becoming a caricature, not of itself but of China where no one dares to take responsibility when things end disastrous and to save face of all involved a full on positive lie is spread to cover up the disaster.
Heck the US is racing towards a Social Credit system with intense data gathering on every citizen like China has been building.
Meanwhile China is becoming a modern variant of a path the USA has been nudged away from: renewable energy based, leaders in AI and robotics and automated factories, Electric Vehicles as main mode of transportation, rapidly reducing pollution (anyone remember the pictures of smog clouds in Beijing of the 90s and 00s? Hasn't happened in a while there, but the US will get that phenomenon in the near future).
And then there is the enormous military growth, from hypermodern systems to upcoming airfighters that keep up with the USs latest offerings, who will buy expensive American weaponry that will be locked down with DRM if the Chinese build and upgrade faster?
Back on topic ... it all started with the utter disregard for the situation of the Iranian government, they would NEVER just surrender because trump said so nor because of a few bombs, if the folks in power in Iran ever dropped their weapons a very angry mob would lynch AND quarter all of them alive, so they can't just step aside, this all next to hegseth just plain underestimating the iranian abilities on home turf because he lives inside that awesomeness bubble.
