Eh. We nuked an Iranian airliner in 1988. News for a few weeks, then nobody cared. The Russians nuked a US airliner in 1983. News for a few weeks, then nobody cared. The Russians plugged another US airliner in 1978 and that shit didn't even get mentioned in 1983. People give far less of a fuck than you think. Expressing outrage permits disinterested parties from having to actually do something about the problem. PROTIP: Sanctions don't matter until they've been in place for years. We've had sanctions against Cuba for 50 years now. We've had sanctions against Iran for 30. Iraq was under heavy sanction at the time of our invasion. And, just as an aside, we didn't even halt grain sales to the USSR after they shot down a plane carrying a standing Congressman.
