It seems that a false flag nuclear attack seems to be planned around September 23 2015. This information is ciphered into media content, just like 9/11 was.
I highly suggest you watch this video. It contains very clear signs pointing to the date of September 23, 2015, and refers to a nuclear bomb, for instance, Obama saying in one of his speeches that he fears more about a nuclear bomb on NYC Manhattan than an attack from Russia or Iran. Or an episode of the cartoon American Dad in which 3 false flag events are announced for 2015, and the first two of them have been fulfilled, and the only one that remains is the nuclear bomb on Chicago.
Or a recent clip of Madonna, Ghost Town, in which the clip starts with a nuclear bomb on NYC with some very explicit signs. Even the lyrics of the song seem to connect this event to the coming of the great deceiver, Satan.
