What does the river Euphrates symbolize?
Ancient Babylon sat on many waters—the Euphrates River and numerous canals. These were a protection to her as well as a source of commerce producing wealth, until they dried up in one night. (Jeremiah 50:38; 51:9, 12, 13) Babylon the Great also looks to “many waters” to protect and enrich her. These symbolic waters are “peoples and crowds and nations and tongues,” that is, all the thousands of millions of humans over whom she has dominated and from whom she has drawn material support. But these waters are also drying up, or withdrawing support.—Revelation 17:15; compare Psalm 18:4; Isaiah 8:7. re chap. 33 pp. 238-239 par. 10 Judging the Infamous Harlot
This is the worldview of some in theology. Most people don't underpin elections from a theological standpoint, but to each his own.
