In 1848 there were revolutions across Europe from Portugal to Poland. The whole continent was griped in a euphoric state. The world thought that with the coordinator of the oppression, the Austrian Metternich, gone, then their demands of liberty and representation would be met.
However the successful revolutions turned inwards after their national oppressors where gone. Petty squabbling and inwardness made the European revolutionaries miss the bigger picture: the oppressors co-operated and worked in plans to crush them. By 1949 all revolutions were crushed through a combination of divide and rule and support of oppressive kings to their fellow oppressors under pressure. As a result the revolutionary fervour and the legitimate demands was converted into anarchy. terrorism and communist ideals
History echoes warnings for today's revolutionaries. Tunisia and Egypt are not safe if the Lybian revolution fails, while the mutual defence pact of the Arabic gulf is aimed to allow cross military interventions to crush future legitimate demands.
The fact that Europe fails to intervene under the pretext of colonial echoes (but really due to the incentive of petro-dollars by dictatorial leaders)is a tragedy that will come back to haunt us. Terrorism is in part the side effect unrealised demands of freedom of expression. Short run economic benefits of not supporting change will be wiped out by the result cost of policing increased terrorism.
