North Korea Fires Another Round of Missiles

North Korea has fired off another round of missiles (http://www.reuters.com/article/topNews/idUSSEO14165620090526?sp=true). This following the first round which occurred around the same time as their recent successful nuclear test (Berman Post: North Korea Detonates a Nuke).

Could this be in part to show the world that they really do not care what Obama (or the rest of the world for that matter) has to say regarding their weapon program?
