Is this show of force by Trump due to a real threat by another country?

Is all this chaos what american Christians wanted? Did they intentionally vote for Trump because they believed him to be the true anticrist? There are so many out there who embrace the end times and want to witness the new coming
of christ. Maybe they know something we don't or their bat shit crazy.

Everyone seems so focused on what the trump administration is doing in the open. What is happening that we don't know about?
