How to truly cripple Russia in their war with Ukraine?

I’ve started to think on a couple things or actions that could be taken that would be both disastrous for the world, but also do serious damage on some alliances that serve one another to supply weapons of war and other aid. Keep in mind, I am not fully informed of all the nuances

You need to ask yourself a few questions to begin with.

Russia is being resupplied a lot of tech and munitions from non embargo supporting nations. North Korea starting to manufacture and send their munitions to restock Russia’s armaments. China has essentially opened a “line of credit” for raw materials, the flow of which has been reduced because of international pressure on China from sanctions, internal economic crisis that has had The People’s Party print and pump money into their economy to try to salvage, and simply their own ambitions to build up their military to retake Taiwan and all of the South China Sea.

I’m not aware of any munitions or aid coming from India at the moment, but they are supplying money for oil and natural gas through avoiding honoring the West’s oil embargo of Russia. Nor am I aware of anything coming from Brazil either.

But one of the most fragile, given the present situation in the Middle East, is the relationship with Iran.
