In 2014, Russia annexed Crimea from Ukraine. This was the first time since the end of the Cold War that a country had annexed territory from another through armed conflict. Russia's intervention in Ukraine has been widely condemned, but it has also been met with approval in some quarters. Some have praised Russia for standing up to the West, while others have welcomed its involvement in a country they see as being in chaos. 

The Russian war on Ukraine is a case study in how a country can successfully fight a hybrid war. India can learn from Russia's experience in several ways. 

First, Russia has been able to use a combination of military force and political pressure to achieve its objectives in Ukraine. This has allowed Russia to make significant progress in the war, while avoiding a full-scale military conflict.

Second, Russia has been able to exploit the fact that Ukraine is a divided country. This has allowed Russia to play on the divisions within Ukrainian society, and to use these divisions to its advantage.

Third, Russia has used information warfare effectively to influence public opinion in Ukraine. This has been done through a combination of traditional propaganda and new media tactics.

Fourth, Russia has used economic pressure to force Ukraine to make concessions. This has included using energy supplies as a weapon, and using economic sanctions to cripple Ukraine's economy.

Finally, Russia has used diplomacy to gain international support for its actions in Ukraine. This has included using the UN Security Council to block international condemnation of Russia, and using bilateral relations to keep other countries from taking action against Russia.

All of these factors have contributed to Russia's success in the war on Ukraine. India can learn from Russia's experience, and use these lessons to help it fight its own hybrid war.
Overall, there are many things that India could learn from the Russian war on Ukraine. While it is not something that India would likely do, it is important to know that it is possible. Additionally, India could learn that Russia is not afraid to use military force to achieve its goals, that it is willing to work with other countries that have similar interests, that it is not afraid to stand up to the West, and that it is a country that is willing to take risks.
