Defense is a legitimate thing to worry about. For example, Vietnam defended itself against America. We do not defend, we attack and pillage resources from the global south. Real defense is honorable and to be celebrated. However, the US military is not an institution that does those things and they cloak themselves (well until recently) in rhetoric designed to confuse the public.
Seems that sending a bunch of people with guns/bombs/etc to another country is almost always bad.
The military doing good things like ... um ... helping out during natural disasters or genuine peacekeeping is entirely a rare thing.
