Poland & Estonia Have a Very Good Point.
It's to the annoyance of Poland and Estonia because bilateral energy deals with Russia are in direct contradiction of the requirement that EU negotiates as a single body. Putin's aim is to divide and conquer, and Gerhard Schroder has done his best to enable this. If middle & eastern European countries see that the western countries won't stand with them, then they'll be forced to cut the best deal they can with Russia; when this happens to all EU countries it leaves them all at a disadvantage.
