It's always important to follow the money during a time of war. You shouldn't discount that as being motivation to start a war.
It's all the Federal Reserve system. Since 1913, the Fed has been the root cause of all of our wars. Think of this, a banking cartel that is the central source of currency for a thriving industrial nation, run by the wealthiest names to rise from the smog of the industrial revolution, people with all the money in the world and had become motivated by power.
"Power corrupts. Absolute power corrupts absolutely."
Wrap your mind around this: When America goes to war, it's forced to lend money from the Fed, with interest! And understand that the Fed is a PRIVATE company! It's not even exactly one with the government and is, in fact, unconstitutional since it's stated that our government should not have a central bank! hahahaha Look at all they've been getting away with for a whole century! They laugh at us in their sleep, knowing how manipulative we are. We're like a giant tank of water to them. Waves crash and settle but if they rise high enough, they'll crash right through the glass. But they try to play God, they try to decide when and how the water settles. They try to control nature and destiny.
An early childhood memory of mine is Puff the Magic Dragon. I saw this scene in the movie then, but now I understand it completely...
(Talking about the living black couds that cover the ''sea of the starless skies'') "They're jealous! They're jealous of the stars. You see, the stars can fly a thousand, thousand times higher than those clouds can even image. And so, like all small spirited and stupid beings, they believe that they can deny beauty by hiding it."
