Is it permissible to benefit from bank loans with fixed fees, given the infidel occupier's seizure of the Muslims' treasury, the weakness of the Sunnis in Iraq, and the dominance of the other sect that benefits from these loans to support itself, all with the aim of establishing a work that pleases Allah and benefits Muslims?

If the expenses on loans are fixed and reasonable, and are considered administrative costs and not a cover for usury, then there is no objection to taking such loans. However, if they are not so, then it is forbidden usury, and it is impermissible to borrow with usury regardless of the lender or the place of borrowing, because dealing with usury is forbidden.
