Logistics is one of the most reliable ways to defeat an enemy, always has been and probably always will be. It's why I'm baffled by the insistence on the US military leaving NATO and its NATO allies. The presence of the US military bases in Europe and east Asia are a large part of what allows it to project power globally. Removing the bases (or severely reducing them) would lead to a self-destruction of US logistical capabilities and eliminate or severely hamper its ability to be a global military power (setting aside the remote possibility of using nuclear weapons, which, if used, would lead to many, many more problems even if they initially lead to military success).
This is what happens when the president was a reality TV star and a Fox News host runs the military. We usually have competent and qualified people making these decisions.
