My Apologies, the credit should go to you for making this observation.
If you follow the posted links you will find that Robock is still heavily involved in studies regarding the effects of nuclear winter - which probably is in itself a noble cause.

What you will also find interesting is that his trip as a US citizen, but under non diplomatic status was so well received in the communist state. He even went on to brag as to how he managed the trip abroad, via Canada, which further does credit to how this man operates.

My personal opinion of what this trip was really about: Robock marketing geoengineering to Cuba.
To bring them on board as an open invitation to join the tight knit group of international club collectivists and to show Castro the benefits that Cuba would see in regards to their own population issues.

It is not up to me to decide the fate of Mr. Robock, however my personal opinion of someone who has whore'd themselves out to sell a project which masks eugenics as a side if not direct benefit, does sit highly on my list of people that I wouldn't mind seeing "dealt with" regardless of their other accolades.

We won't go too far into my opinion of the hubris with which these "involved" scientific community members carry, let alone the fact that they continue to lie about ongoing open air testing.
Far too much "stakeholder" and funneled taxpayer money has been spent on full scale, open air "modeling" already, for them to abandon a continued push for SRM. I guess they will continue to lie until the public just up and forgets that it was actually already underway - when legislation is finally rammed down our throats - just like several other back door, international treaties have over the last 40 years.

The bottom line, Governments and the involved scientific community will not admit to past and ongoing operations. Even if Geoengineering SRM is pushed through by legislation - it will still remain a threat to everyone's safety and is just another potential vehicle for a weapon of mass destruction.

It should not be allowed period!

It will only be a matter of time before one or several groups gather resources and act unilaterally to remove what they perceive as a personal threat in the skies. I personally hope it does not come to this, but it may be the last and only way to gather the proof needed that chemtrails are real.
