On the thirteenth day of the war, Biden's message finally came: it will be more expensive at the gas station.

Making decisions that make gasoline more expensive is a surefire way for an American president to become unpopular.

When Joe Biden appeared on the first day of the war on February 24, with the first sanctions, he also pointed out in particular that oil and gas supplies from Russia would not be disrupted.

Now President Biden has completely changed.

Britain is following suit, albeit gradually.

And already last week, many oil traders, shipping companies, banks, insurance companies voluntarily stopped dealing with Russian oil.

Oil giants such as Exxon, BP, Shell and Norwegian Equinor are getting rid of their interests in Russian oil extraction.

The basis of the entire Russian economy

It's about oil they have earned billions of dollars over the years.

But now they do not want to risk that their oil becomes fuel for Russian tanks in Ukraine, or that their customers suspect it.

Ideally, the US would have wanted to bring the EU to a halt in oil and gas.

It would have been worse for Russia, which sells 60 percent of its oil to Europe.

Oil and gas exports, in turn, are what the whole of Russia's economy is based on: a third of GDP comes from oil and gas.

It can thus be said that Europe is pumping money into Putin's war in Ukraine, by continuing to buy oil and gas.

Can be really much higher prices at the pump

But less oil from Russia means rising oil prices, and thus even more expensive petrol and diesel for ordinary people and ordinary entrepreneurs.

And an oil and gas shutdown would be far worse for the EU than for the United States.

The EU's oil refineries are adapted to partly Russian oil, and it is difficult to change.

Without Russian oil, gas and diesel prices could be much higher than at present.

Still, it is the lack of gas that would be worst.

Without Russian gas, there would be energy chaos in Europe, with sharply rising electricity prices and perhaps rationing.

Tuesday's announcement from the EU to shrink imports of Russian gas to a third until the turn of the year, it will already be difficult.

China a question mark

Conversely, gas and, to some extent, oil are a powerful weapon for Putin.

He himself can choke it straight off and cause energy chaos in Europe.

If Putin is lucky, he can sell his oil and gas to China instead.

It is still unclear how much China wants to help Putin.

China wants to be an economic superpower.

It requires trade with the United States and Europe, which you can not bump into too much by helping Russia.

Regardless, the United States and the United Kingdom are now in need of more oil, from somewhere.

There is talk of sanctioned Venezuela and Iran, but above all, both Biden and Johnson are cheering for increased oil production at home.

May lead to new, climate-safe extraction

Biden spoke about the 9,000 permits to pump oil in the United States that are not currently being used, and that the United States must become self-sufficient in energy.

Admittedly, he went on to say that Americans need to switch to electric cars to avoid worrying about the price of gasoline at the pump.

And that thus tyrants like Putin could no longer use fossil fuels as weapons.

But in fact, Putin's terrible war in Ukraine could lead to oil extraction, hitherto considered too expensive and insecure in the light of climate change, starting anyway.

President Biden's final clip on the speech about the oil stop to the press felt, unintentionally, consistent:

- And now I'm off to Texas.
