I just found this small article in the USIP Special Report on "Terrorism in the Horn of Africa" dated January 2004. A bit dated, but interesting given recent events between the USG and Eritrea and overall US Policy in the GWOT.

Eritrea’s inclusion in the “coalition of the willing” threatens to widen the gap between moderate and radical Eritrean Muslims due to the regime’s use of the “war against terrorism” to eliminate all dissent.

Outlook and Recommendations

The United States fostered democratization and constitutional rule in Eritrea from 1991 to 2001. In 2001, when democratizing Eritreans demanded constitutional governance, the U.S. decision to refrain from taking an unequivocal stand against the systematic elimination of pro-democracy advocates sent the message that only acts of violence and terror—not democratic reform—will bring about change. Current U.S. policy in Eritrea vacillates between two poles: unconditional support for a regime that joined
the “war on terror” and episodic signals of disapproval for the regime’s crackdown on dissent.

U.S. policy should disengage from the increasing authoritarianism of the current regime which has alienated the majority of its civilian—secular and non-secular population. Failure to do so may lead to growing support for more militant elements within EIJM and the ENA.
