I don’t believe he was being entirely truthful.
The US had said all through late January and early February that if Russia attacked Ukraine proper, as opposed to Danbass, the west will coordinate a freezing of Russian foreign reserves and severing of russia from SWIFT.
The US said it publically abs often enough that it has to be seen that there is a high chance the US would follow through because it would be very embarrassing for the US to make such threats and then make it hollow,
This is something putin should have realized very clearly because he was in the middle of wanting the US to realize his threat to attack Ukraine would be followed through because it would be very embarrassing for the russia to make such threats and then make it hollow. he certainly must realize the US is in the middle of doing same with threats to freeze russian foreign reserve and cutting off swift.
Had russia been able to quickly overwhelm ukraine and install a pro-russia poppet government in ukraine, say within 2 weeks. the move to freeze russian foreign reserve and severe russia from SWIFT would not have lasted long. The fact that war ended with little casualties means outrage at russia would quickly fade. The slogan of reducing reliance on Russian gas and oil will also quickly wear thin. Soon russian gas and oil will return themain negotiating leverage back to russia, and russia can use conditional delivery of oil and gas to pry frozen foreign reserve out of the hands of the west, and insist on restoration of SWIFT.
So my conclusion is Russia factored the freezing of its foreign reserve and its cut off from SWIFT into its profit loss assessment of a successful invasion of ukraine.
Where they went wrong is they did much less well during the invasion of ukraine than they anticipated and as a result was unable to wrap up the ukrainian “special operation”. So western hostility is daily becoming greater, while the day when russia can regain enough leverage with its oil and gas to reclaim its foreign is receding beyond the edge of foreseeable future.
I think the reason why the russian foreign minister would now claim to a domestic audience that freezing of foreign reserve and cutting off of SWIFT was unexpected is simply to detach the link between the fact russia would be unable to reclaim its foreign reserve and restore SWIFT access in the foreseeable future from Russia’s abysmal performance in ukraine and inability to put the war behind itself and behind the world’s focus in the foreseeable future.
Instead Russia would like to refocus discontent that might arise from its poor military performance into anger towards the west for supposedly going beyond the pail and taking extremist measures in its treatment of russia.
