NOTES: 

The wiki page for the American sinking of the Kursk lists the time for the torpedoing of the Kursk at 11:29:34 a.m. - 11:31:48 a.m.. The Kursk was sunk off the coast of Murmansk, where the time is 3+ GMT. The original U.S. Navy report, as reported on CNN, for the torpedoing of the Kursk was 07:28:26 am GMT and 07:30:42 GMT. Which means that the Kursk was torpedoed at 10:28:26 Murmansk or Moscow time. So, who is putting disinformation on the wikipage?

The North Tower goes down at 10:28:22 a.m. EST. The Kursk is sunk at 10:28:26 a.m. Murmansk local time. Which means these events took place in the same five second interval of a twenty-four hour day. There are 86,400 seconds in a day. There are 17,280 five second intervals in a day because 86,400 divided by 5 equals 17,280. There was only a 1 in 17,280 chance of the North Tower being imploded at this time. The implosion of the North Tower at this time was not an accident. It was deliberate. Another interesting fact about the 911 attacks is that they took place on the two year anniversary of the Moscow Apartment bombings. These bombings, utilizing time bombs, were attributed to Chechen terrorists. The destruction of the WTC was a retaliatory time-bombing for the time-bombs the USA set off in Moscow two years prior. The North Tower was chosen because it symbolizes the North Pole and the Kursk was sunk near the North Pole.

CLINTON SAID OKLAHOMA CITY BOMB WAS A "MIRACLE OF TECHNOLOGY"

This is more evidence for the OKC bomb being a nuclear weapon.
