And here is a link to the full WEF report:
I would add a sixth "top threat" - the WEF itself.
Doesn't it seem to you like the WEF has become the REAL global government? After all, the UN does not have the power to tax, and most of its initiatives are blocked by the US. Not so with the WEF - they can tax us all they want (indirectly via their pricing structures), and they seem to boss the US and everyone else around with impunity.
And one can hardly call the WEF open or transparent. We get to see what they want us to see, and although many of the attendees were "elected" by someone (e.g., corporate shareholders), they certainly are not a global representative government. They seem to be more like an oligarchy or a developing feudal system of governance.
