1. Can Russia's energy card reverse Europeans' attitude towards the conflict between Russia and Ukraine, or prevent Europeans from helping Ukraine? I don't think this is possible.
First of all, I want to tell you: at present, the most resolute and beneficial support for Ukraine is: Americans and Eastern European countries. Americans have nothing to say. The longer they fight and the harder they work, the happier they will be. Anyway, it can not only consume Russia's strength, but also completely control Europe and weaken its autonomy.
In addition, Americans can test their new weapons in this conflict. Didn't many people say that Americans were manipulated by domestic arms dealers? According to this theory, Americans have no reason not to fight. The longer they fight, the happier the arms dealers will be. Anyway, the Americans didn't send troops this time, so there was no anti-war sentiment at home.
It is also very understandable that eastern European countries strongly support Ukraine. Everyone knows that the lips are dead and the teeth are cold, and the rabbit is sad. Once Ukraine falls this time, it may be Poland and Baltic countries next time. They may want to play for themselves.
To say the least, even the remaining European countries will not help Ukraine. As long as there is assistance from eastern European countries and the United States, it is estimated that Russia has no chance of winning.
Many people say that winter is coming. If Russia is completely "dead", Europeans will probably not survive, and then they will change their attitude. I think this possibility is almost impossible.
There are many natural gas suppliers in the world, which are not exclusively owned by Russia. If Russia chooses to "choke out" Europe at this time, then other countries will occupy this market, and it will be difficult for Russia to come in again.
2. At present, Russia does not want to completely turn against the whole European country, once it completely "dies" Europe. Both sides will be completely torn apart. Everyone has seen Russia's performance since the conflict. It is not good for Russia to turn its face completely-it seems that gas supply has resumed recently.
3. Russian oil price is limited, foreign trade almost stops, and it is severely sanctioned. This is an economic blow. Don't forget that fighting is the most in need of economic support. If you have no money, what can you fight with? Russia continues to export natural gas to Europe, at least with some economic income.
As for many people, once Russia gives Europe a complete "dead air", European countries will be timid and even "freeze to death" in winter. This is obviously wrong, not to mention that they still have natural gas reserves. Even if not, people can still live in winter. Really can't burn coal, can't burn wood, rich people can completely change places for the winter.
On the whole, I think: it can't be said that Russian energy brands will be completely ineffective, but the effect is extremely limited.
