It's been over 30 years since I first read it, but I just reread Siege by Edwin Corley. It's about a military takeover of Manhattan by an army of black revolutionaries in exchange for a black nation in (get this) New Jersey.

I remember when the author was interviewed on a radio show about 1970 or so when it was published. Of course, the novel's storyline reflected the political/social times. It caught my attention again because I thought all you need do now is to substitute Muslim or Arab for black and you have a story with currency.

Some of it is quaint. It refers to IBM Executive typewriters, M-1 rifles, F-104s, TWA, and Whitey. Still, it's an interesting little novel and you might want to dredge it up and read it. For those of you who know New York city, you can probably navigate the geographical references better than I could.
