If you have funding and marketable skills, you only need to cross once into a nonextradition country especially a corrupt one where with funding you can buy a new identity and move on with life either there or in a third country under that new identity. Stay out of places that finger print scan for ID which is most of the EU but Latin America, Asia, Africa is wide open for those with say a new identity from Russia or Ukraine if you are a white guy. It’s not hard to buy papers in Russia heck it’s not hard to buy papers here in the USA millions of illegals have them and use them everyday.
I’m not exactly sure what “funding” this guy has, or what marketable skills he has. He’s not a renowned whistleblower like Snowden or a Hollywood misfit like Polanski.
Kazan is probably a step up from Siberia. They have a lot of oil industry there, too. Really nice Russian city with an educated population, Ikea, etc. Close to Moscow, too. I find that part of Russia interesting. It’s a bit exotic with all the different ethnic groups and big cities you’ve never heard of.
I met a Russian roughneck in my travels and he showed me a video of his rig on his phone. It was a blinding snow storm and he said it was normal June weather. They don’t call it Siberia for nothing. Haha.
