The American Revolution succeeded, but in order for it to succeed, it needed men, personnel, vision, weapons, strategy, money, time, an overarching purpose, foreign help, and significantly underappreciated, the eventual letting go of the British Empire grip upon America. Our Declaration of Independence made it clear that the signatories of it and major participants in this revolution recognized that they were indeed pledging: "… to each other our Lives, our Fortunes and our sacred Honor." Fortunately, for those that had both the initiative as well as the wherewithal to rise up against England, the revolution was a success, and not only that, ultimately our revolution established a wonderful republic, with strong individual rights, including both freedom of religion as well as the press, along ultimately with material prosperity heretofore never before seen in the annals of history.
However, while the American Revolution succeeded, not every revolution does, and the consequences for both failure and/or for revolutions that go on for years and years, with revolutionary forces sometimes inching forward, and sometimes falling back, are consequential for the people as well as the country as a whole. While it is true that many people within their own country may be dissatisfied with the political as well as the economic and overall freedom contained within their country, it is one thing to complain about it internally with friends or family, and entirely another thing to actually contemplate and more importantly to actively take steps to effect change within their country.
The main problem with being part and parcel of the change that you wish to make within your country is that things for your country as a whole, as well as things for you personally, could get a lot worse than they are presently. Revolutions are complicated, to which once started, the end is often not clear, to which in virtually all cases, the standing government has enormous advantages over any revolutionary force, simply because logistics, military, surveillance, and whatnot strongly support the status quo. This means in almost all likelihood in many revolutions, some part of the current regime must be compromised or accommodated to the revolutionary forces, in order for the revolution to have a decent possibility of success.
The foregoing also implies quite strongly, that often in revolutions, the change that is so much desired, does not come into effect, because the former apparatus of the government must join forces or becomes subsumed as part of the "new" regime, now compromised in values in such a way that as the Who says: "Meet the new boss -- Same as the old boss." So not only do revolutions fail with all the attendant penalties for those that are on the wrong side of the battle, so too do revolutions fail because they fail to adhere to the very principles that brought upon the revolution in the first place.
Our world today is filled with much conflict as well as revolution, to which many times men are quick to take up arms, but not so quick to think through the consequences and the ideals of what it is that they truly want and whether such a want is universal, fair, and just. Any revolution that believes that might is right, is wrong, as a true people's revolution must start instead with the knowledge that only from universal justice applied equally to all, is the very light enflamed that brings freedom to its people and their land.
