When the first gulf war broke out, I still attended meetings. It was amazing the people who had not been to a meeting in years, began coming back and professing their fail. But after some time, these same folks stopped attending again.
These events today, will boost meeting attendance in the short term. When nothing comes to pass, the hard core JWs will revert back to the brain dead state of waiting. The weak will stop attending meetings again.
Same story, different year.
