How can bacteria develop immunities to threats if they reproduce asexually into genetically identical cells?

Wouldnt the cells have the same set of genes and wouldnt there be virtually no diversity?

You would think however there’s 2 additional points to consider.  The first is that bacteria can horizontally transfer genes to each other that can upgrade survivability (i.e. antibiotic resistance) and the second is random mutations that allow for Darwinian evolution.  For this one, consider a mutation that theoretically allows 0.1% of a population to just hang on and survive a certain concentration of antibiotic exposure just a bit better than the rest.  Those few will then proliferate to create a potential new strain.
