Isn't possible that the U.S. wants the E.U. to be more dependent on them than the Russians?
Probably. You don't need tin-foil hats for that: most countries would rather have business for themselves than for another country.
their full 100% storage is only enough for a week or two of gas consumption in normal situation, not even during cold season when consumption increases.
That's incorrect:
Refilling gas inventories to 95% full by November would only cover about 2-1/2 months of heating, industrial and power demand if Russia cuts off supplies completely, according to Klaus Mueller, president of the Federal Network Agency
Secondly they are counting the gas that was supposed to be received from US and elsewhere as part of that storage whereas they haven't sent that gas yet!
I haven't seen this before. Do you have a reference link?
In other words the economic situation is so much worse that we thought. We should expect a much bigger inflation due to this money printing policy in near future on top of everything else.
Agreed. We're pretty much fucked at the moment.
