Ukrainian troops were sent there by Kuchma/Yanukovych team BEFORE Orange revolution.
Kuchma only did so to save face after getting caught shipping military equipment to Saddam. His government was also heavily implicated in the UN Oil for Food scam. I for one will continue to support Ukraine against revanchist Russian aggression even if I don't support their leader. I won't condemn the Ukrainians to imperialist Russian slavery just because a pro-Russian is in charge. I will simply oppose Yanukovych's attempts to serve a foreign agenda at his own coutry's expense.
