As I'm reading this, I want to cry out that no, it is not your responsibility. It is the result of the corruption and power hungry groups.
Unfortunately, I can't say that completely. Everybody is able to make a change in their community. Those changes, no matter how small, do add up. This means that, fortunately
and unfortunately, everybody in the community has a responsibility to make these changes.
Based on my understanding, all destructive conflicts stem from fear. Fear may seem perfectly rational, but it causes people to behave irrationally. Fear comes from a lack of understanding, for example, if we do not understand fire, we have much to fear from it. Since we do understand it, we are able to harness its energy to cook our food, and we can distill that energy into electricity to power our technology. We don't need to fear what we understand.
One way to be responsible for your friends and family is to understand the corruption that brings the wars. I'm not saying that you should take part in it, but figure out what causes it, and work on figuring out how it really works. Once you understand it, you can work against it peacefully. If an army is busy gathering its own food and weapons, it is too busy to fight. Of course, it is very dangerous to deny armed men food when they demand it, but there has to be a way to weaken corruption, and it is usually as simple as not supporting it.
Jeff Lilly, the owner of DruidJournal.net, has recently posted two parts of a three part meditation that he does when he needs peace. The first part is to remove fear, the second, to fill his heart with love, and the third step is to seal it in. It may not bring peace to your entire country, but it may help you in finding your own personal peace. (
