You are equating their expression of opinion about the project with involvement. That's no different than alleging we're involved in North Korea's missile project.
I think you believe this road is far more dangerous, though.
And thats why the Canadian and Mexican governments are involved?
Yup, I mean why should our two largest trading partners be involved in planning "a road" that would connect them to us. I mean only a FREAKING NUT would think that they should be included in the planning.
