They got beaten up rather bad in an war of attrition, and though help from the US was forthcoming for the Battles, followon logistical help and so forth was not.
There was no appetite in the US Congress after 2006 to extend the support President Bush had given Ethiopia.
Frankly, IMO, we need to stop respecting borders drawn up by colonial powers, and in this case, allow Ethiopia territorial annexation and access to the sea.
After all, in 1995 Eritrea was carved out of Ethiopia, cutting of Ethiopia’s port of Asmara and becoming a virtual Islami satrapy of Saudi Arabia, and even sending equipment to Somali jihadis to fight the Ethiopians, sometimes with trainers etc from ....Pakistan!
Thanks interesting.
