Alexander the Great was antiquity\'s greatest commander

[Giannis K. Hoplite]

Replying to Robert's and Paul's objections, why isn't the assurance of supplies a virtue attributed to the commander? Why did he "persuade" and force Greeks and Macedonians to follow him? How did he keep and increased his power after Filip died? And above all,would he be able to "persuade" or "force" greeks and macedonian to re-enforce him,had he not been as successful as he was? Regarding the re-enforcements supplies of Alexander,keep in mind that he was an invading force none the less,and not Rome in defence. Rome that was much more populated than Greece at the time. Why didn't Hannibal secure his position back at home by force of arms or persuation if he thought that his war in Italy was the crucial thing for his country?
Alexander was a kid when he started his campaign,and if his generals and his subordinates both in the army and in Greece didn't trust,love,believe and fear him,they could have easily put someone else on his thone,of their own liking. The mere thing that Alexander survived the throne is a great virtue on its own. A politician's virtue,rather than a general's? Maybe yes in today's criteria,but much more relevant back then.
