US sells/provides/uses so many armaments around the world that it’s laughable to think Russia doesn’t already have their hands on at least a vast chunk of our “tech”. Surely trying to reverse-engineer what they can, as I’m sure any country does to foreign equipment.
Usually it’s the manufacture process of tech that is the “secret sauce”.
I’ll take a crack.
It doesn’t take 20 years to build a building, even a large housing project. If you’re including the planning, financing, management, and value engineering stuff - yeah it takes longer than the actual physical building, but no where near 20 years in total. Unless someone who would say as much is being disingenuos and including all time from concept to completion, combined among all individuals involved.
Also, in previous comments you said they spent a billion a year. Then, in a follow-up comment you said “if they save their money for 10 years”. So I’m wondering if you imagine building a housing project costs 10 billion?
Sounds like if the they are actually garnering a billion a year, building housing should be totally workable.
