For those in the London, England Area, I say ... remember your history with pride!
We do, here in the United States of America.
Just ask anyone raised in Texas.
Or ask anyone raised in New England.
Or ask anyone raised in the South.
Ask anyone raised in California.
Or ask anyone, raised anywhere in our country.
As for changes, you should see the proposed changes some people have wanted to put on the ballot here:
To break California up into three states.
To break Texas up into five states.
To remove the Texas Panhandle, Oklahoma Panhandle, part of Kansas, and part of Colorado, and make it a new state.
To break Michigan up into two states.
Those are just the ones I know of.
Of course, if such measures were taken, politics would demand other compensatory measures be taken in other states (that is, more states would be broken up or new states created from bits of other states.)
Locally, they proposed breaking up the county I live in, into 3 counties plus one independent city!
The measure never got on the ballot, though.
So yeah, here in America they are always trying to rearrange things.
The biggest rearrangements occur when the cities grow and expand into neighboring municipalities.
For example, the Statistical Metropolitan New York Area now includes:
All of long island.
All of New York State below the city of Newburgh.
A part of the state of Connecticut.
Most of the state of New Jersey.
A small part of the state of Pennsylvania.
And at the rate New York City is growing, southeastern lower Michigan will be a part of it's Stastical Metropolitan Area in about 200 years.
By European standards, 200 years is not a long time.
