It's not silly 'cause the West based their foreign policy on such assumptions. It's silly in hindsight, but this was all real back then. India was seen as the enemy.
Russia is not in the right, nobody is in the right. Russia's actions are merely justified from an outside perspective, relatively speaking. For example, the Iraq war and the attack on Libya are far more wrong than the Ukraine war.
If you make a list of all 21st century wars and rank them based on how wrong they are, then Iraq and Libya would top the list, and the last would be Ukraine. Only the war in Afghanistan was fully justified.
So, since we live in a hypocritical world, we don't see the West as the arbiters of what's right and wrong.
As our FM Jaishankar said when he was questioned about it, he basically said the West has no principles.
It's common sense to us. A vast amount of Indian land is in the control of Pakistan and China. The West absolutely does not care at all. So why should we care about the West?
