> MH17 was shot down by a Russian anti-aircraft missile, killing all 298 p.o.b. with no consequences for Russia I don’t think this is a good example, given that the act is widely considered to be a mistake. The US shot down IR655, Soviets KL007, Ukrainians S7-1812, Iranians PS752 ... it happens. MH17 is egregious (as was KL007) for a refusal to admit blame, but hardly a casus belli, despite the tragedy.
