That works exactly as long as such an US-aligned company doesn't enter the spotlight in some sanctioned entity related trouble.
Had friends working export compliance for a larger US IT company, and they once (temporarily) blocked a larger shipment to the (British) Royal Air Force because some bozo abbreviated them as "RAF" - which, obviously!, refers to the (German) Red Army Faction, a left-extremist terrorist cell that wasn't relevant for more than 10 years at that point (and wouldn't know what to do with high performance computers, anyway).
Better safe than sorry, otherwise you mess up one day, come back to the HQ on the next and all that's left is a brand new parking lot.
