I don't think most people really understand why the West is (more or less) organised, developed, peaceful, democratic (more or less).
And I wish there was a simple answer. But the list of factors just keeps growing. There are many lands in the world where nation states just will not start up, no matter how much aid is given nor ordinance be dropped.
Well, we don't have to look to far to see historically what happened. There generally were a whole bunch of people with money that had a common enemy. Then they started up a war by themselves. Large geopolitical foes of the enemy then dropped some cash and troops to help them along.
Winning is a bit random (depends a bit on the relative strength and will of the large geopolitical forces), but if the small country won, the country needed to be rich enough to survive without the support once the large benefactors lost interest. Those that weren't rich enough to begin with basically reverted and it all started over again. This implies that you can generally never expect poor countries develop into a peaceful democracy by an armed conflict as part of a larger geo-political struggle (although they might be able to make a peaceful democracy by themselves).
This is probably why there cannot be peace in the middle east. As long as it's a geopolitical war between large parties, even if one faction were to emerge victorious, if it is not naturally economically self supporting as a democracy, as soon as the benefactors lose interest, the power vacuum will be filled by forces that are largely tribal because that is where the residual economic base of the region comes from (economic power begets political power).
Penniless student protesters don't make a democracy. Monied interests make a democracy (or a cleptocracy, depending on your political view). The "peaceful-west" is an illusion, in the west there are major geopolitical conflicts that have involved the west all throughout the short history of democracy, it is simply that they have not recently touched our shores because of our economic/military might. Strength (economic and military) keeps the relative peace, democracy simply allows the tribal factions a temporary pressure outlet. Without the economic might to drown the dissent, democracy simply isn't enough of a pressure relief. You can't give a country an economy (or democracy), they need to learn to fish...
