They lease you land.

But I really can't think of anything produced in Russia besides weapons, rockets, and nuclear powerplants.

About 50% of Russia's exports are oil-based, but they also export a significant amount materials from mining and logging, as well as food and refined chemicals.

I recently came across replacement electron tubes for guitar amplifiers that were "Made in Russia" by a company of the name Sovtek.

Seems like Sovtek is part of a US cooperation (New Sensor) these days. The tubes are still "Made in Russia", though.

My country is full of Russian machinery equipment (lathes etc.), as a result of clearing trade during the cold war. Not as precise as the Western stuff at the time, but usable. And, well, we've got em' by the ton..

They are some of the only people still making sidecar motorcycles. Not the greatest quality, but fun to drive.

where do you live? obviously you wouldn't see any russian things in US for many reasons...

Why not? You see US and Chinese products in Russia and Ukraine, why not vice-versa? "But the dollar is so expensive", etc is not a legitimate argument.

Russians buy American cars, tools, etc.

What does this have to do with anything? My point is if you don’t have russian products in the US (for whatever reasons) this doesn’t mean other people don’t have russian products

“Russia is the 16th largest export economy in the world. In 2016, Russia exported $269B and imported $180B, resulting in a positive trade balance of $88.6B. In 2016 the GDP of Russia was $1.28T and its GDP per capita was $24.8k.”

Take a look at the composition of the export. What part of it high tech?

They'll collapse into a 3rd world country unless they modernize and diversify their economy.

See Venezuela. Except with nuclear weapons.
