^^^ The US and Nato are already in that war.
For those who don't know, Russia calls Ukraine a "puppet country", a puppet state controlled by Nato and the US. The reason behind Russia's serious opposition to Ukraine joining Nato is because by joining Nato, both Nato and America representing Nato will have the right to build military base directly in front of Russia. If this is realized, then what will be colonized will no longer be Ukraine now, but Russia by the European Union coalition.
Key words, after studying the problem, Russia's war agenda with Ukraine contains the following aims and objectives:
1. Russia does not want Ukraine to be used as a military base by NATO and America.
2. According to Russia, the provocateurs and damage to the nations of the world are America and NATO. Because since ancient times the countries that joined NATO were colonizing countries. All nations on this earth.
3. Russia prohibits other countries from interfering, Russia's domestic political affairs with Ukraine, if other countries intervene, don't blame the world war3 will take place because there will be a nuclear war.
Conclusion: so that a nuclear war does not occur, America and its gang of NATO, immediately leave and go home. And don't try to build a military base in Ukraine which is adjacent to Russia because it will cause a major nuclear war havoc and no one can prevent it. In my opinion so.
