Ukraine is evolving more and more as a huge problem for the EU. That may sound paradoxical but - despite anything that all those alleged "experts" might say about current "gas crisis" between Russia and Ukraine - it is nothing else but a piece of internal matters of Ukraine itself! I know quite a lot of people in the very Ukraine and many member-states of the European Union who speak all to a man that this crisis could easily be settled (and it almost was settled between the two presidents of the two involved countries) if it had not been for Ukraine's PM Yulia Timoshenko.
This smart woman is employing all her might to sort it out with her internal rivals mostly. Basically, it is she who throws a monkey-wrench into it. As a matter of fact, there was no exact problem and Ukraine was ready to pay for Russian gas by mutual agreement. Yet it was exactly Yulia Timoshenko who did not except it and virtually rattened putting it through. What Timoshenko really might be aiming at is to oust people close to Ukrainian president Viktor Yushchenko (like his brother Peter Yushchenko) from Ukrainian gas business and from management of such gas enterprises like RosUkrEnergo - the company that handles gas transit from Russia to the EU. Of course, Yulia Timoshenko does not care much either about average citizens of Ukraine who come to suffer from what she is doing, or the blotted reputation of Ukraine in the EU. Ukraine's becoming more and more discredited which means that foreign companies and corporations would think twice before making investments into Ukraine. That’s the result of Timoshenko intrigues mainly. As a primer she’s irresponsible and not relevant IMHO.

Now, Timoshenko is a challenge for EU and Ukraine’s stability. She is to be put into her right place. Next EU move should be to take over the control of Ukrainian gas transit industry even though it requires introduction of troops in Ukraine! We need energy security and we cannot rely on Ukrainians anymore that's why we've got to take control over it which may be done only in cooperation with the other concerned side - Russia. That's the only solution that I can suggest right now. Am I right?

Yes,you must take West Ukraine which never been in Ukraine before russian-german after WW2 agreements and Russia must return their native land of East Ukraine with Kiev and russian Crimea,then EU will be safe from any agressions or provocations...
