Twitter and cell phones can be important for spreading the words--but they won't stop bullets. The attitude of the police and the military, so far in our history, remains decisive.
I don't for a moment see this as some kind of "Arab Spring," that's just some nonsense of the jargon type of which news media are so fond. Certainly, this is just my opinion. In the most succinct form, that opinion is that little has changed, and there is still a good deal of water to run under the bridge before we can know just how important these events are. Twitter and cell phones didn't help the Persian kids in the street over the last couple of years.
It should be noted that it cannot be said with certainty, at this time, that anything substantive has changed in Egypt. That yet remains to be seen. If there is a revolution in Egypt, it ain't over--not by a long shot.
Unless and until there is a public statement about constitutional amendment and elections by the military leadership, we just don't know. I certainly hope all of that happens, but so far we don't know; and it is ominous that people are asking for the constitution to be amended rather than just taking steps to amend it. It is evidence that they are still powerless.
But no, Egypt is not gonna suddenly join the first world, or even be a highly developed and functional democracy for a long time and it all depends on just what you think is a big deal or not.
For them, the period we should be thinking about is not 1989, but rather 1848, when a cascade of revolutions engulfed Europe only to be extinguished by forces of the old order.
There will NOT be regime change in Syria this year
There WILL be regime change in Yemen this year.
There will NOT be regime change in Bahrain.
There WILL be regime change in Libya this year (though it may take the form of a divided country temporarily).
Do you think this COULD be an "Arab Spring"?
I think you are overestimating the "education in Western countries" factor. Only a tiny minority managed to get it.
A more educated youth, but educated in their own countries and more open to global influences via the media (internet included) has to do more with the change of attitude, IMO.
