My personal thought is that the launch from Washington State was an interceptor, not the enemy's launch (enemy being quite likely deep state globalists). But that's just an opinion. for all I know, they were launching a satellite at that hour.
My initial thought had that scenario too. What I find puzzling is the complete lack of other images of the same event, although it was in a highly populated area with numerous potential witnesses, even at 3:56 in the morning local time.
The 2010 sighting of an odd missile launch 35 miles off the coast of southern California north of Los Angeles had numerous discussions online, with multiple witnesses commenting. This one, no witnesses other than the weather guy, who has now 'recanted'. Very fishy.
