I think this is what Theland may be referring to.
//And at the time of the end shall the king of the south push at him: and the king of the north shall come against him like a whirlwind, with chariots, and with horsemen, and with many ships; and he shall enter into the countries, and shall overflow and pass over.// Daniel 11:40
I assume he thinks Russia is the King of the North. I’m not sure who he thinks the King of the South is.
