I once ran a searx instance and understand it. I don't think the hosting location of instance matters much. The underlying search engines configured in the preferences limits/determines results you will get. All the engines available in searxng seem to be from NATO aligned countries. Yacy is a decentralized engine that can provide some mixed results depending on what operators choose to crawl.
