What happens to the Russian/Northern Confederation after the treaty is made with Israel?

Les teaches that the Russian or Northern Confederation of Nations will invade Israel shortly after the treaty was made, contrary to the Antichrist’s idea. God will destroy them on the hills of Israel, so it will be a quick removal of those nations as enemies of Israel. This happens early in the seven-year period; later, as the seals are fulfilled, one-fourth of the human population is destroyed, the two witnesses are killed and brought back to life at the midpoint, and the Antichrist defiles the temple and forces the Jew to worship him.
