Does that mean that Aurvandil has won? Unless they do something stupid - which they're not doing right now - they won't lose Candiels. All they have to do is wait and not attack. Eventually Madina will grow so bored with the whole non-event that they'll accept peace so they can fight a real war or do, well, anything other than sit in the Tower growing old. The only problem with that theory is that Aurvandil seem equally fond of attacking the Tower, which could result in a catastrophic turn of events should they take a major loss again.
Staring match.
Ask yourself what Madina was doing before the war, then revisit whether the current situation is boring in comparison
