I fail to see how the chaos in Ethiopia can be "good" for Eritrea, considering that when your neighbor's house catches fire, your first impulse is to help them put out the fire and stop the flames from reaching your own house. The truth is that no country can enjoy stability and economic growth either in isolation or without the cooperation of its immediate neighbors, and no other people in Africa understand this fact more than the Eritreans who're fiercely resisting neo-colonialism.
That truth doesn't always apply, if your neighbor is menacing you, if he is sharpening the knife for you, then you have something to gain if his house burns down with the whole family in it. I feel Eritrea has a lot to gain if Ethiopia were to crumble like a house of cards. That's in the short term, in the long term everybody will lose, including all the neighbors of Ethiopia. Meanwhile the eritreans are now most concerned about the pain Woyane is causing them, they are not interested in the long term pain that can result if Ethiopia falls apart.
I agree with you on that...the simple fact is the GOE/PIA and the TPLF/EPRDF/MELES aren't really all that different. The only difference is with shabia what you see is what you get..they don't play the game(being two faced) that the other neighboring countries do. But when you look at the facts, bashir, meles, museveni...they've all been in power the same, they all have no appetite for dissent. They've all been backing supporting rebels from neighboring countries etc. In Eritrea's case, the US and meles/ethiopia ganged up, and get the other useless countries to join in the gang-up.
Having said all that, the simple fact is Meles has been a thorn in Eritrea's back for the last decade, if meles/ethiopians had been the slightest bit mature about it, the conflict with Eritrea would have been over a long time ago and right now, relations between the two could have been very good.
If meles/ethiopia hadn't acted like a spurned/burned ex-wife and simply allowed for the demarcation of the border, all this bad blood would not have existed. But because of the way meles has behaved, it's really come down to us vs. them, battle to the death. The simple fact is that sheabia is more mature then meles/eprdf, if you look at the conflict with yemen, or sudan(which Eritrea had accused of attempting to assassinate PIA) in both those instances Eritrea lived up to it's word, gave the disputed territories, while with sudan, it's made peace and bashir has come to Asmara numerous times. So long story short, PIA could have let bygones be bygones and dealt with ethiopia/eprdf if the latter was willing to do the same and let bygones be bygones. But that hasn't been the case.
So, unfortunate as it may sound, so long as Ethiopia insists on trying to push Eritrea into a corner or push it around, the more we will fight back, and situations like this which may be bad for ethiopia(ns) could be good for Eritrea.
I, for one would be happy if meles dies, or lives on, creating a chasm in the ethiopian leadership that would mean them(the US, and other neighboring countries/lackies backing off, or a potential shift in the dynamics of the horn.
