...Except Bajorans enlisted in the forces of an enemy of the occupying force. In analogy, Cardassians should be enlisting in the Dominion military, rather than the UFP or KE or RSE ones.
That is an utterly absurd statement, but if you want to think of the UFP as an enemy force to the Bajorans, go right ahead... I shan't stop you.
I actually question it in the opposite direction. It's natural the Bajorans would join Starfleet who helped them get back on their feet after what the Cardassians did to them.
The Dominion were responsible for what happened to Cardassia and were the occupying force, the Federation helped them to get back on their feet, and were the enemy of the occupying force. Now maybe the Romulan and Klingon prescence and aid could be akin to an Occupation, but, I certainly wouldn't expect the Federation Prescence to be seen in that light.
