Does Les teach that there is a conspiracy to destroy or bleed America dry?
Yes. The context records a longstanding suspicion that a conspiracy exists to destroy the United States of America and states that suspicion remains. It further describes a conspiracy to bleed America dry, pointing to industry leaving, foreign oil suppliers, and the revival of the ancient Roman Empire.
Les teaches that he had said for years, ever since he was a young man, that it almost seemed as though there was a conspiracy to destroy the United States of America, and he still thinks so. He connects this to the post-World War II Marshall Plan, which rebuilt Europe with American dollars, and then to industry leaving, oil coming from foreign suppliers, industry farmed out to Japan and Mexico, and the steel business nearly gone. His best word for it is a conspiracy to bleed beloved America dry, all to enhance the revival of the ancient Roman Empire, now called the ten nations of the European community. He places this in the end-time picture, where the revived Roman Empire or United States of Europe is the beast, and a human leader, the antichrist, receives power from the dragon, Satan.
