What Will Be The Trigger Event to Start The Collapse

I have been thinking about what and when the trigger event will be. And when the collapse comes how long will it last? Are we in the trigger event now and it's just a slow slide into the collapse. I lay in bed at night and think of what could start the whole think. If you read the news you can see about ten different things that could be the start of the collapse. Iran getting nukes, rise in violence in Afghanistan and the US push to go into Pakistan and the H1N1 Flu and the push for us all to take the shots with this and much more I feel as if the end is so near. I prep just as much today as 5, 10 or 15 years ago. I just feel a little better about my preps today. I don't ever think I will feel like I'm done or I'm 100% ready. I just read and watch the things that happen in this world and prep just as always one day at a time. And I think everyday what will be the trigger to set this whole thing off. Keep your eye's open and your powder dry, because the NWO is coming and they never sleep.
