I just want to quote RK’s book on this matter because it is so striking that in our lifetimes we are seeing both the greatness of the US and now we are seeing the beginnings of the downfall.
”The 20th century was called the American Century for good reason. It is as if all nations have lived under the shadow cast by the antitypical Egyptian cedar. Because of empowering and educating the common man and tapping into that vast reservoir of human creativity the American system has unleashed the greater human potential and brought about astounding discoveries and inventions that have benefited all of mankind. By elevating its citizens from the level of serfs and attracting ambitious and brilliant emigrants from around the globe, by fostering development, research, and an entrepreneurial spirit and by building an extensive infrastructure, the American system has developed into the most successful and prosperous economic system ever devised.
Apparently that is what is meant by the water source that feeds the Egyptian cedar—waters being a biblical symbol for peoples and nations, hence: ‘Waters were what made it get big; the watery deep caused it to grow high.’”
and then,
“‘TYRANTS OF THE NATIONS WILL CUT IT DOWN’
It is a fitting illustration, then, that the various trees in Eden should logically symbolize all the nations on earth up until the time Jehovah himself becomes king; whereas Egypt represents the leading nation—as if the grandest tree in the entire garden of God’s planting. However, when Jehovah’s work nears completion the nations are to be cut down—felled just like timber—beginning with the grandest tree in Eden! Ezekiel 31:10-13 foretells: “Therefore this is what the Sovereign Lord Jehovah says: ‘Because it became so tall, lifting its top among the clouds, and its heart became arrogant because of its height, I will hand it over to the mighty ruler of the nations. He will surely act against it, and I will reject it for its wickedness. And foreigners, the most ruthless of the nations, will cut it down, and they will abandon it on the mountains, and its foliage will fall in all the valleys, and its branches will lie broken in all the streams of the land. All the peoples of the earth will depart from its shade and abandon it. All the birds of the sky will live on its fallen trunk, and all the wild animals of the field on its branches.”
The prophecy goes on to state that although the greatest tree goes down first, all the national trees are destined for “the land down below”— Sheol, the pit of death: ‘This is so that no tree near the waters should grow so tall or lift up its top among the clouds and that no well-watered tree may reach up to them in height. For they will all be given over to death, to the land down below, along with the sons of mankind, who are going down into the pit.‘“
