It's not even close to near. Those people are trying to sell books and DVDs.
The four beasts in Daniel 7 describe four kingdoms. You are likely already familiar with it; so i don't need to explain the whole thing. What some people get wrong is that they interpret then as a secession of great empires instead as four great empires that exist on Earth at the same time. If you examine it closely you'll that they have to be contemporaneous. And if you look around at the world you'll notice that this does not resemble the current geopolitical situation. How long would it take to go from the current ~100 countries to just 4? A long time. So the Rapture won't happen any time soon.
