Why is HF not a strong acid like HCl or HI?

If you recall, Dr. Lavelle stated that the strength of an acid is determined by two aspects the first being how easily it gives off its H+ and the second being the stability of the remaining anion. In the case of HF, the anion would not be as stable as HCl because Cl- is able to withdraw much more e- density.

My TA said it's because F has a smaller atomic radii

but its IMF's are greater in the HF than the others due to higher electronegativity right?

F- is not stable in solution and would react with the H+ ions in solution taking them out of solution.
