ISDA - International Swaps and Derivatives Assn.

The ISDA meets before the G8 and NATO summits, over Walpurgisnacht in Chicago. (Apr. 30-May 2)
According to this article, this meeting is before the others because this is where the banksters meet, then they set the agenda for the politicians and military guys who meet at the other meetings.  Here's a quote:

Well, these Masters of the World will be having a themselves a get-together to plan the future of their world.
*The ISDA 27th Annual General Meeting will be held on April 30-May 2, 2012 in Chicago.
*This will be followed by the G8 summit meeting in Chicago on May 19 and May 20.
*Then this will be followed by the NATO summit in Chicago on May 20 and May 21.
During 9-11, it was said that our security services failed to connect the dots. However, here we have a situation where if you analyze this carefully, it is easy to connect the dots.
There is a reason that the ISDA meetings are held first. The G8 and NATO events are the window dressing for public consumption. The real decisions will be made by the money masters so their meeting needed to be held first. At this meeting, the money masters will develop their marching orders for their puppets, the paid servants who are the political leaders who will be in attendance at the G8 conference.

The article also said that because the ISDA consists of big banks that trade in derivatives, and because the ISDA determines whether a credit event is a default, they basically won't hurt themselves by calling default on anything if they can help it.

JPMorgan Chase, Citigroup, Bank of America, HSBC, and Goldman Sachs are the major banks holding the majority of credit default swaps in the US.  This is where the real power lies, unless you look further upstream to the likes of Evelyn de Rothschild or old man Rockefeller.

Anyway, if you fancy protesting in Chicago, you may consider this earlier date instead of the G8 date.  But I don't think protesting is wise.  It never gets anything done but to tie up municipal resources and make arrest records for the protesters.  If it's a news stink you want from protesting, the news lasts a minute then they try to distract people with stupid things like Snookie or the Kardashians.
