I honestly believe from speaking to many crew before these votes that a. they didn't know what they were voting for and b. they were sure a yes vote would just be a show of strength and force WW to back down. They were led to a cliff by BASSA in my opinion and , sadly this is where they are now.
If a. they all knew what they were voting for and b. they thought it may lead to this then we wouldn't be here now, and ALSO, I do not believe that 6000 would vote the same way again out of 11000 possibly left in the aftermath.
