I will elaborate a little on the plot as it really does apply to today...

The military is looking for "the one" who is intelligent enough to command the "fleet" and win against the "buggers".

the buggers attacked first (two different wars)

the buggers are controlled by "queens" and every other bug is just an extension of the queen. Just like an ant colony one might guess. If the queen is killed, the others all die. This is the same thing as the "smiths" in the Matrix. Basically, the "sheeple" in this world would be the same as the buggers in my opinion.

Ender is lied to and manipulated into defeating the entire race of bugger queens. After he destroys them, he realises that the buggers didn't know that they were actual intelligent lifeforms until it was too late.

He feels remorse and guilt and betrayal.

To me, this might be the same as how those in power treated Jesus Christ - using him to manipulate the population and eventually destroying him and manipulating his words to retain power.

While this is going on, his "brother" and "sister" manipulate the world population by deceit and lying - creating a war at home and then solving the war and being a hero at the end and the brother is the ruler.
