I have never understood the argument that Russia somehow has leverage over Europe by providing us with gas. Russia has never once broken or even threatened to break its contracts for political gain. What leverage did Russia have before? Europe was the party that unilaterally chose to terminate the contract and stop receiving Russian gas. The Russians never turned it off even when the Europeans were supplying Ukraine with weapons to kill Russians and commit terrorist attacks inside Russia.

And yes, there are a few leaders in Europe who are more on the pragmatic/opportunistic side, but at the moment the hard-line Russophobes are very dominant. They have gotten their way nearly every time so far. The only exception being the recent rebellion over the theft of Russia's reserves. We will see if the situation becomes desperate enough that more cracks start to show, but so far Europe has shown itself repeatedly to be willing to destroy itself for the sake of its ideological crusade against Russia.
