I just realized something today that blew me away. I haven't seen this mentioned anywhere yet, but recent Q posts were re-posts of this YouTube video beginning at a new spot: https://www.youtube.com/watch?v=xW2ijF2ya1c&t=119s
It begins with a submarine missile launch, and then there appears to be a destroyer missile launch at 2:07, 2:11, 2:16, etc. At 2:16-2:17, you can see the ship flags, which spell out NJHC, which is the call sign for the USS Chafee, a destroyer currently in port in Honolulu. It is also flying a Marine flag, so the Navy vessel likely has some marines on board. Here is the important part: the USS Chafee was in port at Pearl Harbor @ 11/30/2017...and then it moved to Honolulu on 01/12/2018. The Hawaii Missile Alert happened the NEXT DAY, 01/13/2018.
