"Adolf Putin is desperate enough to sell gas to EU" so Putin would be desperate to sell gas and Germany would help him out by buying it, because the rules of the mafia world? And knowing that beforehand, he blows up his own direct pipeline to Germany so they'd have to ask permission and pay Ukraine or Poland to transfer more gas to Germany? Did i understand you correctly?

As far as US pushing EU to diversify its energy resources from RU, now you're starting to open up your eyes, think macro level and ask very dangerous questions. Careful, real world is not pretty and dangerous questions might lead to disillusionment and why everyone cares about Ukraine all of a sudden.
