Because there is no such endorsement.
Because modern political dynamics is simply different from that occuring 3000 years ago.

The thing is, salvation HISTORY simply doesn't make sense if god's self-revelation abruptly stopped with the acts of the apostles 2000 yrs ago, does it? Nor would it make any sense if it were presented independent of the millieu in which it happened, would it?
In fact, god's self-revelation, from the same dogma you are so averse to, is an on-going process. Heck, even science is a venue fo god's self-revelation.
Yes, it is so complex and you are arguing from a position of ignorance.
