I think the situation would greatly improve. The Egyptian people have proved they are capable of organizing themselves and taking care of their country in spite of the regime's efforts to sabotage them. Without the regime standing in their way, the Egyptian people would be even more successful.
You probably think I am romanticizing the situation. But I don't think so. Consider this: right now, the "whole government machine" is inciting violence and spreading chaos. The government has deliberately abandoned providing security for neighborhoods, security for the National Museum. The government deliberately released criminals. The government hired plain-clothed thugs to attack protesters, to loot houses and businesses, and start street wars. In short, the government is trying to spread instability and violence, and oppose democratic reform. On the other hand, the people of Egypt have organized themselves into neighborhood defense committees for security from criminals and looters. The youths of Egypt, though they were unarmed, defended their nation's heritage at the National Museum from government thugs by locking arms. Doctors gave out free medical care and volunteers provided sandwiches and water to the protesters. Volunteers cleaned the streets. The people proposed a rational, practical course to democracy, which the regime has opposed at every step. Leaders of the protests urged nonviolence, while the regime urged violence.
So yes if the whole government machine gave up and went home tomorrow I think things would improve, including security and stability.
well i guess we will have to speculate on that one as its not happening
What happened when the British got up and left the colonies? The war ended. Peace and order were restored. Local people organized themselves into militias for security, much like the unarmed Egyptian "security committees". They sent representatives to ratify a national Constitution, which was ratified SEVEN years after the war ended. The process was peaceful because the people were united on the METHOD of government -- democratic elections -- which allowed them to resolve the fierce debates over particular matters in a peaceful and orderly way. I expect the same would happen in Egypt if the dictatorship would get out of the way.
