It depends, I think Syria was a half hearted involvement, I think Bosnia we did actually do some good. Anyone know why Russia and China can’t be involved/lead a UN peacekeeping effort? Why block it, dictatorships good is their only thinking?
I would suggest not continuing to fall for it. It's not that war and intervention can't ever do "some" good. It's that the people behind wars and interventions are never interested in actually helping people. It's purely for money and power.
