I don't' know why people take Russia's bluffing so seriouslyAlso @McTwerk on a purely political level, while strategic cost is low for Russia, its not exactly a preferred political outcome. They'd surely rather no strike at all, symbolic or not. For one it creates the impression of regime weakness and that the air defenses can be circumvented. Its why theyre talking tough in their media response to the strikes. Russia also has its own domestic political considerations as does the regime.
They got tricked in WW3 talk
