They are moving a lot of aircraft, but how much munitions?
I've seen an Israeli estimate that the US has enough bombs for 2-3 days of sustained combat and maybe a week at a lower pace. A C-17 or even a C-5 only carry a few aircraft bomb loads and with the transit distances can't sustain a prolonged fight. The US does have pre-positioned fleets of freight ships in locations such as Diego Garcia, but I've seen nothing to suggest a maritime support effort is under way.
If they do attack it will have to a short targeted decapitation campaign against the government and IRGC.
Meanwhile, arrivals continue.

USAF United States Air Force - Middle East Activity 25 February -
Coronet East 044/046/047
There are three active Coronet missions this morning. "MO" F-15Es being moved under CE 044, "HL" F-35As under CE 047, and CE 046 with unknown receivers.
CE 045 resulted in two "SJ" F-15Es from Seymour Johnson AFB arriving at RAF Lakenheath yesterday evening.
This is all excluding CE 051, with another six "FF" F-22A Raptors from Langley AFB arriving at Lakenheath late last night.

Cell 1:
Boeing KC-46 Pegasus 1x #AE5E13 17-46038 - CLEAN 43
Boeing KC-135 Stratotanker 4x #AE013B 57-1435 - CLEAN 41 #AE037C 63-8026 - CLEAN 42 #AE058D 58-0016 - CLEAN 44 #AE04FB 57-2605 - CLEAN 45
Cell 2:
Boeing KC-46 Pegasus 1x #AE5F92 18-46039 - CLEAN 53
Boeing KC-135 Stratotanker 4x #AE04B4 57-1499 - CLEAN 51 #AE0389 62-3514 - CLEAN 52 #AE0503 60-0336 - CLEAN 54 #AE0669 62-3540 - CLEAN 55
What looks like two cells of fighters from Hill AFB have departed this morning. Four groups of tankers have departed from the U.S., with an additional tanker for each cell departing RAF Mildenhall. CLEAN 41/42 and CLEAN 51/52 departed Hill Air Force Base, each likely with six F-35As in tow. To meet them will be CLEAN 43/44 and CLEAN 53/54. Once they cross the atlantic, CLEAN 45/55 from Mildenhall will likely collect the twelve jets.
I'd expect the Hill tankers to return, and most likely at least one of the second group for each cell.
