Hey, if America was good enough for Jesus, it's good enough for us!
...anyway: people have been making these sorts of predictions for centuries. There are endless Bible verses that can be interpreted to match the world's circumstances, and lots of visions and dreams filled with symbolism that is just begging to be applied to whatever we want.
What surprises me the most is that the people making these predictions are very much aware that others have been doing the same thing and failing every single time. But they are confident that they are the exception and that they will get it right. In some cases, like the WTS and people like Harold Camping, they keep making predictions even after they got it wrong!
The more things change, the more they stay the same.
