It looks like none of that is connected. Thanos never wanted to invade earth. It's as if they wanted to distance themselves from Weadons vision as much as possible![]()
Thanos was invading worlds and killing half the population....he used the same army on Gamora's world as he did in "Avengers". It's possible he wanted to kill off half of Earth and The Avengers stopped him....which is why he said he knew who Tony Stark was in "Infinity War".
Not saying they had all this planned out back then....but it does connect.
