I took it as a struggle against oppression and a fight for freedom. I think the ending was a warning to not become that which you despised and fought against to begin with.
...which is a hopeless effort. Trust me, that ALWAYS happens.
At most, a society can hold it off, but only if the society is also unsuccessful in being secure. Notice that the USA was quite secure for decades. That security came from strength and that strength generated political power worth fighting over. That fight drew the unscrupulous and criminal to grasp the power on offer. That leads to tyranny every time.
