Where else? not only we have the highest divorce rate but also the highest crime rate. In some countries if you get a divorce you can't get remarried. You are done for life. This rule deter ppl from getting divorce.
United States by far has the single highest divorce rate compared to the rest of the world.... almost more than the rest of the world combined, unfortunately! Personally I believe the biggest reason is couples rushing to the alter before they even know a little bit of the personality of the significant other they're about to marry. After that, I think it's because it's almost a trend or the "style" of America's newer culture/mentality. Compare this to almost the entire world and its a whole different ball game! So much so that in those cultures, divorce is more taboo (even for the victim and victim's family) than rape, forced marriage, murder and etc, etc, etc.
