I thought the bajoran attitude towards the feds was explained in the second episode of season one .The bajorans may have been pretty hostile towards the Feds only after the bajorans kick the cardies off their planet does the Fed offer assistance ?I would be pretty ticked too and be very wary towards any so called help.
Didn't the provisional Government request help from the UFP, rather than the UFP offer it?
And it's implied in the pilot that the Cardassians where all too willing to come back when Bajor had something of value again.
