There are the laws of science... Such as thermodynamics.... But there is one lesser known law. One I have named after myself. I call it Amanda's Law. It states, that violence is a cycle. Once started it is deeply hard to stop and once started it only grows in it's severity and terrible impacts.
I understand why India did what it did. I am not sure I can fault them. At the same time.... I don't think it accomplished much but creating more animosity that will be visited back on them later down the line. So do I think it was helpful or that it resolved anything? No. I think India would be better served by finding a non violent response to these things. Something that would still be impactful. I think Israel, needs to look at it's cruel policies. I think Palestine needs to have an election and get rid of Hamas cuz they are just violent and nutz, and kidnapping people is evil (yes I would tell the same thing to American Ice.) I think Ukraine, has no choice but to defend itself. In their situation there is no other alternative unfortunately. As for Russia, Putin, needs to take his mental health medicine as he has clearly lost his mind during the covid isolation.... Being insane is not helpful to world peace. The USA, loves conflict. That orange sickophant is trying to start another one threatening the Ayatollah. Which is NOT helpful either for world peace.... We have a long history of starting stupid wars on a foundational equivalent of a giant pile of horse turds. So, yeh, we need to take a hard look at ourselves which is difficult to do when nearly half the country can't see the problem we are and the problems we have and think wars make us great....
What makes societies great, is their ability to see the humanity in other societies. Their willingness to practice peaceful disagreement. It isn't always possible. But the vast majority of the time it is. Their preference for focusing their energy on constructive projects that serve the world rather than projects that destroy and or tear others down. Conflict will happen.... But it is how we deal with it, that says the most about us. For example, The Whisky War, fought by 2 of the most peaceful nations on earth I believe it was Norway and Canada, had a dispute over an island used by greenlanders for fishing. Territorial dispute Canada thought it was theirs. They would leave rude letters from each trip to the island and plant their flag and leave a bottle of alcohol for the other side of the conflict. When they would show up they would plant their own flag rip out the planted flag leave some booze and a rude letter. Finally, they worked it out diplomatically. Not a shot was ever fired. This is the best way to "fight."
The example you have given was of Denmark and Canada, and yes, it's high time that Palestine gets rid of Hamas, please note that terror organizations are not liked anywhere, and I am certain that most of the residents of Gaza do not want Hamas either (mainly because of the mess Hamas brought them into), so a proper government is very important for Palestine.
Iran possessing nukes is not a good idea at all. Iran is a type of country which won't think twice before firing a nuclear bomb in Israel, if they do that and Israel is unable to stop it then the Balkans and the northern regions of Africa will be full of radioactive elements (not a good idea). Yes operation "Rising Lion" was a necessity
No, I disagree with your view on Putin, had he not invaded Ukraine then Zelensky would have joined NATO, and then American nukes would have been stationed there (That is RIGHT under the population centers of Russia). Why on Earth would Putin want that? In his own perspective he is not wrong, the only way he could ensure Ukraine would not join NATO was to take over it and thus the war. But since you Americans want to get a firm grip on Russia's throat you want Ukraine in NATO, and as a result your opinion (and most Americans) stands here, and one cannot blame you.
