The beast nation is Rome during the time of Jesus, that's how it was able to make war with the Lamb. The "Beast" character is Nero Casear himself.
The Number 666 is a historical numerology Herbrew geneology tracker. It was and still is in use these days. During the history of the Hebrew people they were taken numerous times into captivity and so not to loose their geneology they assigned every character in the Hebrew alphabet a number. These numbers were applied to peoples names.
Although a very needed preserver during it's times in captivity, this numerology is still used as a game in Israel.
The number 666 when calculated, literally spells out Nero Casear.
This is a matter of fact and not a matter of interpretation.
Therefore, it brings about a clearer understanding of who the characters are in revelation. The beast nation is Rome under the Beast Cesar.
That is why Daniel was told to seal the books and John the revelator was told to open them.
