Yes, it does not matter which territory the troops on the transport are invading. The amphibious assault is in the sea zone adjacent to a territory with an airbase, which is all that is required.

So then when can the naval retreat take place. say a amphip assault iis declared, only transports alone, and no ships whatsoever defending. the defender announces scramble. Can the fighter sink the transports before they ever unload? And can the attacker say retreat, without ever making the attack, and to avoid defenseless sinking of ships and cargo?
thanks
One round of combat must be fought before the attacker can retreat. The transports would only be automatically destroyed if there were no retreat route for some reason.
