(A geopolitical perspective)
A boy stands atop a small hill of dirt in an otherwise flat and grassy yard. He is set like a crouching wrestler, waiting for the next assault. There are three other boys taking turns trying to get to the top of the hill. One by one they go up the hill, only to be tossed back down again. A fifth boy lays on the grass, propped up on one elbow, spinning a dandelion head in his fingers, laughing to himself as he watches the action unfold. He is fascinated by how the game progresses.
It does not take for long for the alpha boy on top of the hill to learn which boy is his greatest challenger. He adapts his defense to always be prepared for that one boy. He learns to prolong the struggle with one of the lesser boys so that he can use him to block the challenger when he comes up the hill; waiting for the challenger to get halfway up the hill before pushing the lesser boy down at him. The challenger also adapts his tactics; first to follow the lesser boys in different ways, then to convince the lesser two boys to attack at the same time. But still, the alpha boy adapts along and remains on top of the hill.
Eventually, the challenger decides to lead and coordinates a group assault. They spread out around the hill and all attack at the same time. All four boys tumble down the hill in a dirty ball of arms and legs. The fifth boy considers the moment, feels the urge to get up because the top of the hill is clear for the taking. Even though taking the hill would invite all four boys to attack him, he is fairly certain he could hold the hill; he is the same size as the alpha after all. But, he is comfortable and relaxed and his mother has been yelling at him allot lately for coming home dirty and sweaty.
Now, the four boys are fighting to keep each other from getting back up to the top rather than trying to get to the top themselves. The fifth boy lays back on the cool grass and watches the clouds float overhead.
