I understand your sentiments and see all sorts of reasons that can justify your thoughts.
However, can I suggest that interventions rarely have the desired results.
It seems to me that nations need to often suffer their horrors to revolt against them and produce the people and the resolve to make something better.
It seems cruel I know.
Did the US need its War of Independence and its Civil War. Probably as those events produced a resolve to enshrine a set of rights that persist and a sense of unity that persists.
In Australia, we avoided those conflicts in the main.
So we can consider ourselves fortunate but leaves us with a less "patriotic" fervour. A good thing I reckon.
Vietnam has become a powerhouse of economic development and one could argue it was seeing the communist alternative that inspired them.
So bad can lead to good outcomes and the pain is an accelerant.
It would be nice if it wasn't necessary, but seems sometimes it is.
