Let me re-phrase it to prevent double-meaning: I don't think Russia supplies arms and troops to Ukraine.
I also don't think that it's necessary to supply arms because there are a lot of weapons inside Ukraine, from the Cold War period, would be enough for 2-3 wars. As for the troops - there is also no point, because volunteers from inside Ukraine and other countries, including Russia do come to Ukraine. There are a lot of volunteers from Serbia, because they think they take their revenge against the US for losing Kosovo
Это ничего: ты можешь так думать. Но тогда почему украинские войска ни разу не наступали, только обороняются? И даже оборониться нормально не могут.
