Tariq Ali's reactions, in the Guardian:
The new wave of mass opposition has happened at a time where there are no radical nationalist parties in the Arab world, and this has dictated the tactics: huge assemblies in symbolic spaces posing an immediate challenge to authority – as if to say, we are showing our strength, we don't want to test it because we neither organised for that nor are we prepared, but if you mow us down remember the world is watching.
This dependence on global public opinion is moving, but is also a sign of weakness. Had Obama and the Pentagon ordered the Egyptian army to clear the square – however high the cost – the generals would have obeyed orders, but it would have been an extremely risky operation for them, if not for Obama. It could have split the high command from ordinary soldiers and junior officers, many of whose relatives and families are demonstrating and many of whom know and feel that the masses are on the right side. That would have meant a revolutionary upheaval of a sort that neither Washington nor the Muslim Brotherhood – the party of cold calculation – desired.
The show of popular strength was enough to get rid of the current dictator. He'd only go if the US decided to take him away. After much wobbling, they did. They had no other serious option left. The victory, however, belongs to the Egyptian people whose unending courage and sacrifices made all this possible.
And so it ended badly for Mubarak and his old henchman.
