The latest episode of Citations Needed Podcast (http://citationpod.com/) does a good short review of some particularly agregious situations in which the US military bombs countries then the same or related parties praise themselves for their humanitarian response to the aftermath.
Worse, when you bomb a country, for example, it should be obvious that this sets back all of humanity to some degree. Apparently, it’s not obvious. But Earth and humanity are systems, and this analogy is such that we can look at any other system and find the same outcome. Damage one part, and effects will be felt in the others; often not at simultaneously. Some parts will be stimulated only to be depleted later (like the immune systems in our bodies) and require attention. The US is experiencing this sort of reversal right now, though some are in denial or haven’t caught on to that yet.
