Why Italy could not sustain Ethiopia in World War II

How could Italy have supported its troops in Ethiopia during World War II?

Italy could not sustain its forces in Ethiopia during World War II unless it first took British Egypt. Their isolated position lacked the logistical depth needed for a prolonged campaign. Local offensives sought to distract the British and buy time. Once those efforts failed, the position collapsed relatively quickly. Territorial expansion had created an empire whose possessions were difficult to support in war.
