Change does not neccesarily bring about instability. If there is a role for international community within these issues, it is to help facilitate change and that change willwork for the betterment of the people. Obama has been clear on this issue, change needs to happen but not at the expense of anarchy... something that in this part of the world is translated into sectarian violence every time. Finally tanks and stines analogy is all to easy. It is all to easy to paint simple pictures and claims them as mirroring reality. An army can protect innocents, and if some of the stories being told about what is happening in egypt are correct, this has been the armies main role.
