I think generally western EU has no idea how unbelievably corrupt these regimes (Fico, Orbana, Babis) are... they are not stealing on behalf of Putin, they are stealing for themselves, and they are oriented towards Russia because they dream of having Putin's unchecked power.
Luckily I don't think Fico will help Putin that much because nobody trusts him anymore, his foreign minister is very weak and as you mention Slovakia is no economical heavyweight. The hardest thing for us is to see the brainwashed masses still voting for Fico or worse still actual nazis.
