The secret is the distinction between "tribulation of those days" and the "great tribulation". Had there been no difference then Jesus would not have used such different wording. The "gathering" process meaning of the "Armageddon" meaning, is active now with globalization as its obvious world networking main force. So that conglomeration and the "war of the great day of God the Almighty" are actually also distinct different meanings. Armageddon is a process active even now with global sovereign implications. (Rev16:12-16; Rev17:11-18);
One clue is the "tribulation of those days" resolves as shown at Matthew 24:29, not into the end, but into world seen final milestones first. (Matt24:30-31) And those are quite the milestones not even the "end" yet. Bethel just glosses over all this detail as they also attempt to filter out the "evil slave" warning to keep their own status well sanitized. Thus the "tribulation of those days" is not ending in "the end", but in a global milestone: world government, the "Armageddon" ultimate globalized "product".
So in my opinion "Armageddon" is an ongoing global process that culminates under world government (also a process aided by supranational globalization administrations and super-corporations global in authority), the obvious culmination of globalization. It is a global situation of sovereign conglomeration (in every form formerly governed by individual nations as best they could), it in itself is a seemingly innocuous globalizing process, and the process consolidates world resources for a great recovery potential at the end of the cycle, it is what the conglomeration means in a sovereign sense that is ominous, it is an apex consolidation.
In any event it will takes some final years to wind down the globalization process, it is not the Bethel "slam dunk".
Bethel's premature end delusion is the one at 2Thessalonians 2:1-2 as a signal warning Paul gave to ID the last point of what is now the classic terminal apostasy: right at Bethel, right in the corrupted well veneered leadership. Paul gave these warnings because expert apostates, like Bethel, are very hard to detect for those misled by them, it is a gradual process (Dan8:12, 2Cor11:13-15) but effective by the time it is completing. (2Thess2:1-4; Dan8:23a)
The use of the premature "end" delusion, "to the effect the day of Jehovah is here", what Bethel is doing right now, aids Bethel's concealment with a mental smokescreen, false anticipation and eventual total hoax potential. That is what Bethel is actually creating and thus blatantly "exciting" Jehovah's witnesses, and others, "to the effect" the end is nearer than it actually is. It is the earmark main delusion of the modern apostasy.
Of course the worst "apostates" are not the poor stumbled guys out on the street and in the pews (where Bethel directs focus away from themselves), it is in the central ministerial authority, the same place the big Bible "apostasies" ALWAYS manifested historically. Bethel is no different, connecting them to prophecy is actually logical, but due to its ominous implications it is avoided by JWs and non-JWs alike in general, the cognitive dissonance thing. Yet that is what we are dealing with, and this is how Bethel, though fulfilling all the signals, is so well hidden in comprehensive false perceptions, they subvert both JWs and non-JWs with the "first reaction" assessment no matter how they deploy the illusions.
Bethel will go down long before the overall world system (Dan8:13; 1Pet4:17), instead the world system fully globalizes into world government, and a period of world "peace and security" (invert Matt24:6) and world recovery (Isa41:1) at the end of this drawn out cycle, still yet to start, not end yet. (Dan11:42-45).
.
What ends the overall "great" "tribulation", still many years from now, is God's "repay tribulation to those who cause tribulation" at 2Thessalonians 1:6-10, yet another "tribulation" meaning in the Bible, but the final one. Bethel is just a global waffling act trying to bypass the most significant period and cycle of all human history with their main delusion it will "end any day now". Bethel is what will "end any day now".
