YHWH has a chosen people on Earth today, regardless of whether those 6+ million souls under the auspices of the Watchtower Society are the same Jehovah's Witnesses referred to in Isaiah 43:12, "I have declared, and I have saved, and I have showed; and there was no strange god among you: therefore ye are my witnesses, saith Jehovah, and I am God."
The question is, are you one of God's chosen people? It may very well be that those referenced in Isaiah 43:12 are not all inclusively Jehovah's Witnesses.
Suppose they are scattered throughout the entire world "out of every nation and of all tribes and peoples and tongues" (Rev. 7:9) and not limited to the 6+ million people affiliated with the Watchtower Society?
The book of Revelation in chapter 7, verse 9, rules out an "organization" of people as the authentic Jehovah's Witnesses based on a simple litmus test: Ask the Governing Body how many baptized Jehovah's Witnesses exist on Earth today? If they don't give you an EXACT NUMBER (which their central computer calculates based on the number of baptism filings required from each congregation worldwide) then they will surely state a "ballpark" figure of approximately six million people.
In sharp contrast, Revelation 7:9 refers to "a great multitude, which no man could number" -- in other words nobody is able to offer you any figure at all! Not a million or a billion souls or somewhere between; the true figure when the end of this system finally arrives could turn out to be 10; or 1,000; or 10,000,000,000. Revelation 7:9 puts an end to any speculation about exact or approximate numbers of true Jehovah's Witnesses (as identified in Isaiah 43:12).
When asked about the number of true Jehovah's Witnesses who will survive the war of Armageddon, the Watchtower Society doesn't humbly respond to the tune of "Dunno. There's no way we can tell based on Revelation 7:9. A whole lot of religions besides ours could be amongst the survivors for all we know." Therefore the Watchtower Society unwittingly rules itself out as being the true Jehovah's Witnesses spoken about in the book of Isaiah. Rather, it is just another mainstream Christian denomination that may consist of a number of true Jehovah's Witnesses, just as many other religions (and not necessarily Christian religions) may also contain true Jehovah's Witnesses.
Revelation 7:9 does go on to state about the demographic makeup of this unknown-numbered great crowd of Armageddon survivors that they are "out of every nation and of all tribes and peoples and tongues."
Not only are they from every continent of Earth, but they are from "all tribes". In ancient times various "tribes" would hold a wide divergence of beliefs as we see today. The religious tribes today from Christendom to all the other religious tribes outside of Christianity all believe in God. Each religion is filled with multitudes of good hearted people whose belief in God and love for a Creator of all things, inculcated since childhood and often retractable, has placed them on many roads all leading to the same place. That place is the One and Only, True God, whom the Bible identities as YHWH and other religions identify under different Names.
Rather than forcing billions of people who are Hindu and Buddist and other religions inculcated for generations to change from intractable beliefs by forcing them to accept the interpretation of a publishing corporation as "the truth," millions of angels are now in the process of harvesting this planet to find the meek who are heirs to the Kingdom of God.
The True God is in the process of examining souls to gather this "great crowd" to survive. Survive what? A worldwide destruction that will be unparalleled since the dawn of human history. There is no hurry. Jehovah has patiently waited for two of His "days" or millenniums, and so what's another few more of His days if it means the salvation of those in countries such as China and India, to name but two of many?

And a Heaven in a Wild Flower,
Hold Infinity in the palm of your hand
And Eternity in an hour.
