Jeremiah 50: 9: For, lo, I will raise and cause to come up against Babylon an assembly of great nations from the north country: and they shall set themselves in array against her; from thence she shall be taken: their arrows shall be as of a mighty expert man; none shall return in vain.
When Iraq (where ancient Babylon was located) was invaded by the coalition armies during the 1991 Persian Gulf War, they used smart bombs which were precision guided to strike enemy positions. These were the arrows of a mighty expert man that Jeremiah spoke of so long ago, and were called such because they never missed their targets. When the Vatican (Mystery Babylon) is destroyed at Armageddon according to Revelation 18, it will be hit by an arrow of a mighty expert man; a precision guided missile armed with a nuclear warhead. And to fulfill the seventh vision of the prophet, America will likewise be destroyed by these same weapons.
