Everything I know about Ethiopian politics I learn from reading the papers, Meskelsquare blog, and sometimes the BBC web site (when I have enough bandwidth). That and assorted cab and car drivers.
For those of us who grew up in the US during the cold war, it's a familiar scenario. Back then, everything bad that happened was the fault of the Russians. Everything bad that could possibly happen was a "commie plot" that would come to light eventually (e.g., fluoride in the drinking water as a commie test for poisoning us all).
It's like that here in the papers with Ethiopia and Eritrea. No matter what bad thing happens in one of the countries, it's the fault of the other. When the Islamic Courts Union was acting up in Somalis, the Ethiopian government said they were supplied by the Eritreans. When the tourists were kidnapped in Ogaden, guess who was behind it? Even better, in the Eritrean press guess who is the cause of the dire state of the Eritrean economy? You guessed it: the Ethiopians. Of course as someone who doesn't really know what's going on, I can't say which of these is true and which isn't. But they can't all be true, can they?
If nothing else, it makes for spirited debate. Even the writer of a boring blog meant to keep Mom and Dad up to date about what he had for breakfast can be accused of being a) a tool of the Meles regime, and b) a tool of the Eritrians/Tigrian separatists, all on the same day. Look, if these guys were going to pick a tool, they'd pick a sharper one than this...
