Ukraines main source of income?? oil pipelines that carry oil from Russia to Europe. So old Vlad knows he has Ukraine by the short hairs as it is. He is just posturing so Mother Russia doesn't lose billions. Vlad isn't stupid,,, it costs a lot of money, blood and publlc disapproval to invade an occupy a foreign country. Russia learned this lesson with Afghanastan and Chechnya. Todays world is not like the old days when you caould invade a country, rape, pillage, plunder and enslave.
