Just to be clear I'm not in favour of Russia's war and am not arguing against punishing it for the invasion.
However I have noticed a difference in rhetoric around what seem to me to be similar sorts of economic action (though this could well just be my ignorance talking).
Sanctions against Russia have cut it off from many different resources, companies pulling out, effecting many supply chains.
When Russia, disagreeing with the stance of another country in supporting it's enemy, cuts off oil and gas to attempt to use it as leverage in removing that support it gets called blackmail.
"It comes as no surprise that the Kremlin uses fossil fuels to try to blackmail us… Our response will be immediate, united and coordinated" ~ Ursula von der Leyen (President of the European Commission)
Is there an objective difference between the two uses of economic leverage, that make's Russia's actions "blackmail" and the sanctions against them not?
