This is probably what the Yougoslavian government answered too, but Hitler had nothing better to offer. However, it was a grat strategic oppurtunity: an direct acces to the mediteranena would control Peloponesus and get close access to Pirea (Athens) harbour whereas The adriatic was more like a trap (ask the Italians who got blocked there by the British) . This would also give the Yougoslavian navy an alternative access to the sea.
