Stop dreaming, be serious... Russia took on Georgia and all that was done is few angered letters and it was forgotten.
Seen that video on BBC, even the BBC said that it is heavily biased towards protestors since it protrayed that only the protestors suffered, while the police in the square had numerous losses themselves and protestors have been seen with live ammo guns Before the police were allowed to carry those themselves.
It was also mentioned it has been "hollywood" edited for maximum effect, hardly your average video.
No lol, they will not intervene against Russia, dont be crazy.
Ukranian army is pathetic compared to Russian and chances are that the real army would refuse orders to fight Russians from the government... About 40% of Ukraine are still pro Russian.
