They will end very bad if they commited the error of bombing Russia, thats like suicide.
Georgia did the same mistake in 2008 (killing Russian peacekeepers in South Ossetia), and paid very dearly for that. Georgia 2008 and Ukraine 2014 are very similar. Both the governments fail to realize that the NATO is just using their soldiers as cannon fodder. In case of a war with Russia, the NATO will offer no support at all, just like what happened in 2008.

Russia is a military superpower, it isn't as strong as it was 30 years ago, but still very strong. Any country that tries to attack Russia (or any other superpower) is making a mistake
Ukrainian probably hoping US will intervene. Georgia incident should teach them not to rely on US and Europe so much.
