Yep, having three carriers there sure is working.  Chump is NOT a wus, it's just that the options are very limited.  He is finding out what Bush and Obama learned, there's nothing you can do militarily that would not result in the Korean Peninsula and Japan being being set on fire.  If Chump gives NK an "ultimatum ' the NKs willl respond with another test and the US  will have boxed itself in to a point where it will have to act, against the wishes of SK and Japan.
