That's a ridiculous comparison, the United Nations has nothing to do with Christianity or Islam, to which you are objecting.
United Nations, as a political concept is quite close to how was concieved Dar al Islam or Christianity in Late Middle Ages, as in a sense of political communauty, or rather, tentative to reach it.
Btw how is United Nations so vastly different from United States?
Because US is a political entity, not a continent (It's not because it's labelled on a map that is such)
Also, you do realise there's an actual place named
Dar es Salaam?
Do you realize that Dar al Islam have a quite certain political and ideological meaning, covering all of land of Islam, not only a land in particular at the contrary of Dar es Salaam?
It's like wondering why we can't call one of Jupiter's moon Moonshine because there's already one sattellite called Moon.
If not exactly the same name, it's the same exact concept.
It's not. Dar es Salaam is a name given to paradise, as you can find towns named about biblical names in US, as in
Eden, NY.
Dar al Islam covers all the regions where Islam is free to be practiced (that is, basically, where Islam is dominant) and eventually the sense of a communauty besides political divisions.
Giving the need of being protected and surrounded by other Islamic countries, to have a region being acknowledged as part of it, a far continent, surrounded only by heatens if not Christians, could never, never ever be called such.
