I'd say this is actually questionable. Kim Jong Il probably knew this, which is why when tensions did increase every now and then things were left to cool off before anything major kicked off. Kim Jong Un is still really an unknown entity and doens't have the political experience his father did. Kim Jong Il was groomed for over 20 years before he took power. Kim Jong Un didn't even get 2, and he appears to be pushing things further than his father ever did.
There are a couple potential scenarios of what could be going on behind the scences in North Korea. From whats is going on, my guess is that he believes his father's propaganda about the strength of North Korea. He believes they actually could win and is prepared to go to war. Alternatively, given the limited transistion period, Kim Jong Un may actually not be pulling the strings and his generals my be ruling through him. No one has a clue what these guys are like and they may be eager to go to war given all the build up in the North Korean military over the years.
I've said this on a few sites now, but given that North Korea tends to time things around events in Kim Il Sung's life, my guess is if its going to happen, it will happen on the 15th April (Kim Il Sung's birthday).
