If your sub fails, and the other sub survives you must retreat.
Even if the attacking sub doesn’t sink the enemy’s sub, the transports can still do debarkment.
It needs only that the other sub submerge.
If Italy used their 2 fighters to attack Greece and they moved them back to Italy, can they scramble those 2 fighters if the navy adjacent to Southern Italy is attacked?

Why not? The fighters’ attack takes place during Italy’s turn. When an enemy power attacks Southern Italy scrambling occurs as a defender’s move at the end of the attacker’s Combat Move Phase.
