Inspite of those who claim he has been wrong on prophecy, he has been careful NOT to set dates on anything, only to outline his interpretations of biblical prophecy. One key item that he got RIGHT was that following the fall of communism (early 1990s), he correctly pointed out the militant islam will be the next challenger to democracy, filling the void left by the Soviet Union. He tries to be through in his contemporary research.
But he did not forsee hte fall of soviet communism. In the aftermath of that boogyman's evaporation, he immediately started looking for other scarecrows to cower before.
