The common thing is that there were no desired results because the west decided to do some half-assed thing and just go with the minimum amount of force and troops. Also, some parts of the west decided to start/intervene/participate, while others abstained. In short, nobody cared enough about the goals and about their respective western allies to go in with a heavy force, accept some losses and do the job properly.

Of course circumstances, reasons, participants and histories beyond that were different.
