What Eritrea has done is it has resorted to its old traditions. They have headed for the mountains. What should not really be forgotten is the method and the process that is being used. Eritrea is a sovereign country. So is Ethiopia.
Sovereign countries have disagreements.
They have conflicts. I think as John Harbeson put it, the demarcation of boundaries were delayed, and they were delayed because the two leaders at that point were allies, they were former guerrillas turned into statesmen, but they delayed it. But we should also remember that when Eritrea ascended or became a sovereign state, no one, especially Ethiopia, made claims on those territories. I think it's important to unpack that concept. So what it has made the Eritreans feel is that they, and only they, can save themselves.
