Years Ago wars was about resources and power.
Expanding territories, so yes powers and gaining more people to show their strength and vast lands that they own.
Now it's more likely the revenge of new generation what the another nation done to their older generation.
And long time Ago it was for wealth and resouces mostly.
Now it's more revenge but that's not solution you can not punish new generation for what the older generation done.
Not for revenge, it's still the same and not that much have changed. It's still the same from showing military prowess to gaining more alliance which means security, power and resources.
We all change world Changing and those who are stuck in the old and don't want adapt new mind and let go the old will make their own life more harder.
Off course those who are smart enough let other to fight in name of " revenge" and will come later buying the cheaper land getting good deals of natural resources and secretly playing on the both sides.
So until that old belief system don't change then wars not stop.
That's why it's important to let go old and focus on new and stop blame on whole nation or country for wrong doings of other people in history that's just excuse to continue endless wars it's like you revenge and after they revenge and after again you revenge and after they revenge it will be never stop.
Some countries and Nations off course will use that for their benefits while two sides fight about revenge the neutral sides must tell both sides that they have right to fight so that neutral side can manipulate with both sides secretly.
You got the point here right ?
I got the point but we've been always getting to the point of our roots. While the modern belief have been changing gradually but the roots can't be removed. We're not for the war, we're all for the peace but we can't do anything if our government starts to engage on it and there's always the agenda that they want to have. As the saying goes, "history repeats itself" and with that, we're coming back to the roots and reasons why they're doing this.
