how different is the american democracy from the rest of the world?

Explanation:

Most foreigners from democratic countries have parliamentary forms of government, so there isn't the drama of a "divided" government such as we have most of the time. Historically, it's the way we chose to limit the power of our central government. As such, Washington D.C. is definitely not the center of all American political influence, despite what people who live and work there might think. America is huge geographically; this is the uniform reaction of foreign visitors from most countries – keep in mind that their countries are often much smaller than one of our smaller states, and the very idea that one can drive thousands of miles, all across America, and never encounter a border boggles the mind of most foreign visitors. It's the one thing you hear from most visitors here.

Sarajevo was disputed between Serbia ( who wanted to have power over it) and Austria (who had the power over it at the time).
Franz Ferdinand was assassinated by a Serbian rebel, which was possibly more important, because this led to a conflict between Austria and Serbia, and then to the conflict between Russia and Austria, as Russia sided with Serbia.

Another take on this was that Bosnia (Sarajevo) was an important ground for the two empires: Austria and Russia, as a possible (or actual) sphere of influence and expansion, and it was important for the two powers to show their strength there.
