Nobody cared when Russia put military there last year. Then after Afghanistan disaster in the summer he doubled the amount of military, and still nothing happened in response. It's a highly corrupt country where opposition is in prison, and various foreign leaders launder money there. There is no appetite for investing in Ukraine, meaning multi-billions into real air defences and training military to use it instead we gave some pocket change and wished them the best while using their banks and oil companies as personal ATM.
