Completely different angle: It's worrisome that Russia is now able to concentrate its might on eastern/southeastern Ukraine. I don't want WW III, but it sure would shake their Rooskie azzes up if THEIR OWN country got attacked at a completely different location. But where... and how... and who? Then it hit me:
Ukraine ought to launch a counter-offensive, take the fight right into Russia! I know that limits their credibility when it comes to getting world sympathy, but why does Russia get to do whatever-the-heck it wants, with impunity?
They should go right into Moscow! Get a small, elite force (dunno how many that would be... 20? 50? 100? 500?) and some great weapons that do not have a US label on them and fake their way right to the Russian equivalent of the Pentagon (if there is such a thing... the Kremlin?) and just blow up as much of it as possible!
Then also go to a super-fancy apartment building that might be inhabited by the Russian elite and fill it with bullet holes. Not shells that would explode though, because Ukraine is the good guys! Hopefully kill a few civilians, but not too many. Yes, I wrote "hopefully kill a few civilians". Tough toenails. You know what they say, "War is hell."
Likely a suicide mission, but maybe if they worked quickly and planned it well enough, they could even get their guys out of there.
When they do this, they need to immediately and thoroughly spread a message to the effect of the following: "Hey Russia, you probably don't like having your capital city attacked, do you. Well, now you know how we feel the past month! And you better start defending the insides of your borders, rooskies, because you have no idea where or when the next one is coming! Getting hard to sleep at night now? Try one more bottle of vodka: It seems to be putting your soldiers to sleep." (ok, I'm getting carried away...maybe a slightly different tone).
Basically, pull a "Doolittle's Raiders on 21st Century Steroids".
I can't decide if the above is the worst best idea ever, or the best worst idea ever.
