> The company was always about Wars not Mars.

Such a cynical take! Starlink made Golden Dome possible. It is easy to make up conspiracies post-hoc while forgetting that they were ridiculed when they announced it and the "experts" opined that it is impossible to do.

> SpaceX was in fact founded with the architect of SDI

This is highly unfounded speculation. Griffin went to work for "In-Q-Tel" after SpaceX was already founded (as said in the link you cited). There is no evidence I could find that they ever invested in SpaceX.

The existence of cheap launch and cheap satellites allowed the (at the time new) Space Force to pivot from large, expensive monolithic satellites to a "proliferated architecture" (https://en.wikipedia.org/wiki/Space_Development_Agency#Launc...) at a much lower cost.
