Can teh Us still be classified as the United States of America? Think about it. THe only yime in recent history that we were "United" was when we wanted to go to war. And even then that only lasted under a year. People are divided as it is. Throw in some politicians and you've managed to create democracy. So ask yourself is the Name "The United States Of America" just a name now or does it still have theMeaning it did when created?
There have always been deep divisions. That the name of our country includes the word "united" in the first place is a sign that it is a composite.
If anything, the states are more united now than they have been for most of the nation's history. For a minute there at the beginning, they even had distinct currencies. Less than a century later they were literally at war with eachother.
The rambunctiousness we're seeing these days is nothing new, and tame relative to what we've survived in the past. It's just our style of democracy, bless our hearts.
