Drop the bomb on me, please.
Do you think that if america had not attacked iran and instead tried bombing moscow into submission that could possibly had worked and ended the war already?
Also do you think that if Ukraine would target russia banks along with energy sector that would make a difference?
Yes. Though, it might have also caused WWIII - but since we are heading for it anyway, what is the difference if it arrives a few years early?
Banks are just buildings. To target banks, they would have to hack the servers.
