Many religions are right about Armageddon. JWs as well. But the nature of it and significance of the "place" eludes many. With JW it is the timing that eludes them. JWs think "it can end any day now brothers!!!".
But according to Bible logic, prophecy, and the basic globalization process of the rival world government of humans on planet earth (8th King) a final cycle (Dan12; Rev8-11; Rev16 parallel) and another decade prior to full human international government actually completing is required.
And without that "8th King" actually being a KING beyond a UN "image" meaning (Rev13:11-15), function and scope, there can be no Armageddon. It needs to be a real world government fully empowered internationally, a real 8th King full bodied "scarlet wildbeast". (Rev17:8-18)
So JWs have premature expectations and a stalled theology that will toss them into the beginning of that final cycle as bewildered as the next guy, because it must go on a number of years (Dan8:14; + Dan12:7(Rev11:2-3)) and a few Bible events and world events beyond the JW "deadline" also must manifest as per Bible prophecy and internationalist projections marking the final progression.

So if you are privvy to basic logical appreciation, over the next decade human "8th King" world government will indeed become vocal prior to completion beyond current elite murmurings and low key press. Once the world has passed the "point of no return" for national sovereign power (financially next; (Dan11:42-43)), soon to start the final slide of national sovereign declination into internationalist ascendancy, you can gauge UN centric world governmental totality of international completion by their own announcements.
And that is your monitor to know when an "Armageddon event" of divine intervention could actually be all systems go. As the UN world government completes, that would also trigger Armageddon prelude finalities. (Dan8:25; Dan11:45 Dan12:11; Rev11:7; Rev19:19-21)
So JWs live mentally in 1970 perpetual world snapshot as to globalization awareness as the primary basis of the "gathering" power of Rev16:13-16 as foundational world government power internationally. They got the basic gist of a sort of repeating Genesis 11 "globalism" and divine intervention nature of an Armageddon event on a renewed form of globalized world kingdom (Zeph3:8-9), but they are premature in it's manifestation forecast, and it's basic prophetic requirement to have a completed and announced (1Thess5:1-3) rival world government as full 8th King for Christ's Kingdom to be fighting.
If God and Christ came down "any day now", they would find no human Kingdom ready for battle; (Joel3:9-12).
Thus by plain logic, the 8th King actual world governemt must complete before any Armageddon divine war could even theoretically manifest. And that will require a final globalization cycle for full national sovereign deposition of financial and governmental "power and authority" completely (Rev17:12-18), and that will take a good decade to achieve.
The final cycle can start any day (Dan11:42-45), but it can not end as expected by JWs prematurely, before that final cycle completes.
