I've never seen any reference saying the Rothschilds or the Rockefellers ever had more than a few hundred billion in today's dollars. Compare to the US federal budget, which is over 3 trillion per year.
Generally to understand the history of any advanced civilization you have to follow the money. And since 1815 Rothschild have had enough capital and reputation amongst private investors to decide who rules in most countries, which country has the credit to start a war, which country/alliance has the money to win a war, etc
Dude, that's such an utter cop-out.
