I'd like to suggest they call it ....... Operation Dark Storm!
https://matrix.fandom.com/wiki/Operation_Dark_Storm
"During the early years of humanity's war against the Machines, the leaders of the United Nations found themselves desperately trying to halt the advancement of 01's armies, who were relentlessly advancing and overrunning various nations in Africa and Eurasia.
When the war began sometime after 2139 (approximated based on the end of the Second Renaissance), the Machines were steadily winning against humans. Looking for any way to slow their advance, scientists devised the plan to block the sun's rays from the surface of Earth using nanites sprayed into the upper atmosphere in the hopes of cutting the Machines off from their primary power source.
This "final solution" was code-named Operation Dark Storm."
