This is what the whistleblower website wikileaks has released about what President of Uganda, Yoweri Musevini as asked the then assistant secretary of state Dr. Jandai Frazer to do something about Isaias Afeworki when it comes to Somalia. It says:
“…. Another problem in Somalia was Eritrea, according to Museveni. He described his visit with President Isaias Aforkwi in March and said that although the two promised to talk, they had not communicated since. Museveni said President Isaias was preoccupied with trying to unseat Meles. That was all Isaias talked about, yet Museveni observed that Meles did not appear to be in any less control of Ethiopia despite Isaias, actions. Museveni told Assitant Secretary of state Dr. Jandai Frazer that Isaias needed to be talked to by the members of the U.N. Security Council who carry a big stick. Museveni claimed that Eritrea continued to infiltrate weapons into Somalia and said that Isaias needed to be intimidated. Museveni argued that the UNSC should consider a blockade or sanctions if Eritrea does not listen.
If Isaias was controlled and Somali groups cut off from him, the situation could stabilize. A/S Frazer told Museveni that the U.S. was considering options, ranging from designation as harboring terrorists to drying up financial support, against Eritrea. The U.S. was trying to persuade the Somali parliamentarians in Eritrea to leave before they associated with terrorist elements who sought refuge there.
This would be important to establishing credentials as a legitimate opposition. She asked if Uganda would be willing to accept those parliamentarians that chose to leave Eritrea. Museveni agreed and explained that the wife of former warlord Aideed was still living in Uganda. Museveni,s only condition was that TFG President Yusuf must have no objection. A/S Frazer said that any such arrangement would be worked on in consultation with key players in the political process..”
