In Bosnia, the Clinton administration and the EU provided cover for the Serbs while pretending to do something. This provided a cause around which Jihad movements could coalesce (along with Chechnya) leading to both the "Jihad travel networks" and improvements in international resource flows to sponsor those. Later, during the Kosovo conflict, the Clinton administration bombed civilians in Belgrade and blew up passenger trains, trying to assert U.S. initiative which they had ceded to the Serbs and their patron Russia.

To sibling: why does anyone have to get involved until it hits their borders/supply chains?

Syria was a half-hearted involvement? So sponsoring insurgencies to destabilize a sovereign country would have been good if only the government was also toppled? Iraq? The whole ISIS genocide rape torture destruction and blood letting thing was slightly inconvenient but I'm sure the people of these places will thank the enlightened noble Europeans and Americans for their gracious aid.

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.
