How to evaluate Alexander's crusade

Alexander's crusade was a predatory war. The expeditionary force fought continuously for 10 years, with a journey of more than 10000 Li, and fought hundreds of battles over rivers, besieged cities, mountains, plains and deserts, and established a huge Alexander Empire, starting from the Balkans and the Nile in the west and extending to the Indus River in the east. In the battle, Alexander correctly chose the strategic direction, rationally used Macedonian phalanx tactics, was good at organizing infantry and cavalry, army and navy to fight together, and used both military and political means, leaving a glorious page in the history of world military art. Alexander's expedition to the east caused great disasters to the local people, but objectively it also promoted the economic and cultural exchanges between Greece and Asian and African countries, which had a far-reaching impact in history.
