I don't.
No as Muhammad was not very successful in comparison to other well known generals. Alexander, Caesar, Charles Martel, Qin Shi Huang, Hannibal, Khalid ibn al-Walid, etc. He never expanded out of Arabia, which fall into civil war at his death.
Khalid ibn al-Walid was one of the primary general of the early Muslim expansion into Arabia, its revolts, conquests of Iraq and Syria. His record speaks for itself. Muhammad was a statesman far more often than as a general.
The environment, cultural and religious views, of Arabia at the time would have already conditioned me to accept success as a boon from God. Unless I was a hardline polytheist or Chalcedonian Christian I would have little reason to reject Muhammad. If I were a member of one the Jewish tribes of Arabia it could go either way.
Keep in mind that placing yourself into such a context that is drastically removed from our time but also has limited information we can use makes it difficulty to create a image without bias. The information we do have is usually from the upper class rather than the average person. This information can be easily tainted by a bias in which one is either a "supporter" or one of the "oppressed"
