The ingredients are not there, the US only reacted as a gesture of camaraderie towards Europe. The troops occupying the south did not even proudly divulge that they are Russians
The Ukraine is in no position to fight. There are only two generals in Ukraine who are not Russian speaking and they are in the Western part of the country. Ukraine is also broke and Russia refuses to forward any money to the illegal government in Kiev. The E.U. and U.S. are backing out now that they feel they won, and especially since Ukraine needs money desperately. Even the IMF with its harsh loans is going to wait and see what happens. In addition to Ukraine's woes, the gas discount given by Russia has been withdrawn and Ukraine will have to pay full price. Ukraine owes Russia about one and a half billion in back gas bills, and with the winter still going strong the people are going to be very, very cold. So where is McCain, Nuland and Merkel, they certainly can afford to help them out? Yeah right! The only problem I can see in Ukraine other than the Nazis in Kiev is Turkey. They have their own ambitions towards the Crimea and are using the Tatars for that purpose. They know they have a better chance of manipulating the E.U. towards that end, than they do with Russia. It's a repeat of Syria, where Turkey went against Assad with the hope they could grab a part of it and is now supporting terrorists. In the Crimea they are using the Tatar minority to cause problems, and according to Arab news sources, Turkey is paying jihadists and militants the way they did in Kiev. This might be why Russia took full control of the borders in the Crimea. If perchance this turns into a major war it will probably be with Turkey, because Russia is getting a little fed up. This would have the possibility then of becoming a World War, but hopefully not. As for Ukraine, there is some fighting in the Eastern Ukrainian cities after the Russian flag was raised, and about 170 Russian speaking Ukrainians were injured. Again though the militants might have been Tatar jihadists brought in from Syria. This might also be why the Russian Duma has decided to send in troops. I'm only speculating of course, so don't take my word on it. ...I bet though I'm right? )
Chance of a US vs Russia war? Zero. Hussein Obama is too weak and cowardly. Looking at a map on another forum, Putin's objective here is easy to see. The Crimean peninsula, the Lower Donets Basin industrial area, Odessa, and Bessarabia all voted for the Russian stooge by a 20% margin. These areas are ethnically heavily if not majority Russian. By nabbing those four regions, Putin landlocks Ukraine, takes most of their industrial base and reduces Ukraine to an agricultural protectorate. He doesn't need to occupy central and western Ukraine. He has all he wants and any help will have to come overland through Poland. Landlocking Ukraine means the US - which by reducing its army by a quarter - cannot get maritime access. Not only Hussein Obama look weak, but the balance of Europe looks weak as well. Putin's armed forces and economy are no great shake put with the US in virtual (and increasingly statutory) isolation, Putin in trump all the way to the Atlantic seaboard. Putin has a wonderful window of opportunity. He can run wild for at least twenty-two months.
