How come Elenin didn't break apart during prior passes through our galaxy?

It's already September 20th!  There are SOO many weird things happening this month, and most of it has happened since we've been following this comet Elenin. 

Personally, I've never believed Elenin to be more than a comet making it's way by Earth.   However, look at all those other weird things going on during September:

Reported Solar Flares - Don't forget there was an "unexplained" grid failure in Southern California this month (eventually blamed on butterflies!) right at the peak times of those reported SFs.

Russia and the whole ISS situation... (evacuation? wow)  The whole thing is odd and, well, it's very sudden and we get a rare glimpse of NASA in a state of nervousness. 

There was a crazy sighting over 3 states - a large, slowly moving orange/green meteorite thing that was even seen really clear here in L.A. -

Now we are told there is break aparts, date changes, its gone, no wait, its coming...

Then the Russian satellite is falling, don't forget about that.  Theoretically expected to break apart into 26 pieces...

And falling in to Earth, rather unannounced, on the 26th (later revised to a little soon, maybe the 23rd...)!

Oh then that little nugget of info in the news... Obama is going to be at the Denver Airport  in late September, too....  there happens to be a deep underground bunker at that location.
