This was a group that was pretty homogenous in its makeup, had a strong set of laws and customs, and a common language and religion. Plus was blessed by God. And they couldn't make it work.
The problems were constant in fighting, lawlessness and constant invasion and oppression from neighbors. One of the tribes was all but wiped out in this period by the other twelve. The reason that they demanded a King was because they were tired of getting smacked around by every two-bit nation with an army.
There is no reason to think that we would fair any better. And we don't have the pluses that they had.
Read the book in any case. Some really great stories, Ehud in chapter 3 is a favorite of mine.
