"NATO is an alliance so don't conflate the two. If the US is at war NATO is not necessarily"

NATO is an aggressive military alliance of imperialist powers which is dominated by the US. Sometimes US does the heavy lifting, sometimes NATO.
The US has been involved in all the NATO wars, NATO has been involved in all the US wars, sooner or later from Afghanistan to Libya and bombing of Serbia.

NATO is an aggressive military alliance of major imperialist countries.

That is exactly what it is.
