Re: Has there been a large scale tragedy since 9/11 where...
op is deranged if he thinks such things started with 9/11. This sort of thing basically goes back to the beginning of human history, but only in the past 50 years have idiots been brainwashed into dismissing common sense observations (like that powerful people lie and hide things for sinister reasons) as "conspiracies" (most American wars have required "conspiracies" of one sort or another to get the population to go along with them--look at the origins of the Iraq war, for a recent example)--and covert warfare has been the norm since the 1950s (what world are you living in?); the fact that some person makes a youtube vid about one ridiculous thing does not discredit any other event, each of which should be judged on their own merit--your logic here is just false and dishonest (or idiotic).
Ass Dan would've been there calling Cato a "conspiracytard" for suggesting that the first triumvirate had any ulterior motivations behind it. In history you see "conspiracies" everywhere (e.g. Caesar pretending he was attacked in Gaul first, William the Conquerer leaving England to bring about deliberate instability that he could then ruthlessly crush). Late Rome, for example, was just one conspiracy after another--do you think human beings suddenly changed or something?
