Talking about benefits, I would say war never brings benefits.
War always brings destruction to both sides. And if I say who benefited from this war then I would say Russia. moreover, in all other fields, all the countries of the world are facing economic crisis. I think this situation is due to the introduction of various restrictions on oil and gas.
I am not an expert but I assume there have been companies that own weapons and ammunition factories around Europe, USA or even in China which probably are having a good time since this invasion started against the Ukrainian people, after all, there are already rumors and informs from the USA-Ukranian side that they are running low in ammo which only means that manufacturers will get more money to increase their production and the owners of such factories can pocket a good money our of this situation.
They may not even be interested in the specific situation of the war, but like the extra work they are getting to do for both factions.
