This video was recorded back in April of this year, hence the snow.
The Nimitz is making its final voyage (with a recent detour to the Middle East), before it’s set to be decommissioned and replaced by the more advanced Ford-class carriers. However, a shiny new toy isn’t enough for the US to maintain global influence.
While these massive carriers are a significant component of US power projection, the true strategic advantage lies in the global alliance network. This network provides basing rights all around the world, enabling the US to get around quickly and affordably. If the US continues this current trajectory, the logistical backbone of US power projection would go limp.
