WWI in Europe is how I see the endless war for power. WWII was funded by western banksters. Peace will never be an option until we kill the goose that laid the golden egg.
Learn your history.
WW1 did not end in a victory. It ended in an armistice (they basically got tired of fighting and went home).
That armistice was negotiated in Versailles. The disaster of the Versailles treaty placed an unpayable burden on Germany, allowing Hitler to rise to power.
Hitler funded his exploits by stealing the gold from the conquered nations to fund the next nation. His first exploit he funded with gold stolen from German citizens he considered 'impure' and by violating the terms laid out in the treaty of Versailles. By the time France was occupied, Hitler had basically run short on money, since he was spending it on conflicts all over Europe and in Africa. This is why the Nazi army was stuck in France with little to do but boast about their superiority and have a picnic to pass the time. They did not have the resources to cross the channel and invade England. They could harass her, and they did, but they could not invade her. This set the stage for the eventual buildup and deployment that became known as D-Day.
In other words, WW2 was caused by the treaty of Versailles. It could be properly called a resolution of WW1, rather than a separate war. Again, Germany started the war. Again, she was defeated.
The allies paid for their side of the war through their own treasuries and taxes.
The horrors of WW2 are well documented.
One of the aftereffects of WW2, which is still with us today, is the abandonment of gold and silver as a currency (by theft in most cases) and the implementation of fiat currencies. This happened to all of the Allied nations AND to Germany, since the cost of WW2 caused their governments to go broke. It happened to Japan and Russia as well.
The cost of war is high, and not just loss of lives and property destruction. Those weapons and armies are expensive, and war aims to be destructive to both.
There really is only one basic cause of war: theft. Even wars based on religious conflicts are about theft. Tyranny itself is based on theft.
The way to peace is a simple one: profit and capitalism.
People don't attack their customers.
