There will be military action, but without a declaration of war!
The declaration of war entails legal consequences such as the mobilization of the population, the imposition of curfews, and others. If war is not declared, but simply fighting is underway, this gives more room for maneuver. Declaring war on countries in conflict is not accepted and is very dangerous. Let's recall Iraq or Yugoslavia, there was no state of war there, everything was done by operations to enforce peace or impose democracy. But by no means a declaration of war. Without declaring war, a State can be recognized as an aggressor that invaded the territory of a neighbor with whom it had good neighborly relations, and it recognized the people's right to self-determination.

Declaring war on a state can have negative consequences. In this case, economic ties with other countries, even with those that support them, immediately begin to crumble. Thus, sanctions may be imposed, and the implementation of UN sanctions will be closely monitored. This can also have consequences up to and including expulsion from the UN. And yes, a country that has been declared at war can be officially helped with the approval of the United Nations, so to speak, by the whole world.

Europe will be left without resources. The collapse of the EU. The loss of U.S. influence. The Beginning of China's Growth
After the collapse of the USSR, Europe gained access to Russian resources for a song, actually selling goods made from Russian resources to Russia. Now, if Russia wins, relations with Europe will deteriorate, it will not receive resources, and China has already received the Russian market at no cost, European companies themselves left it without a fight. In addition, Europe will have to rebuild Ukraine, because it was Europe and the United States that pushed it to war. Many people in the EU will not like it, and they will start leaving the European Union. Becoming poorer, Europe will buy fewer goods, including American ones. Russia will begin to recover at the expense of the former Soviet republics. China will grow.

If Russia loses, it will be plundered.
