rewriting history

this is the second time in my life that i feel i am a witness to history being made...
for a student of social sciences, ideology is an important aspect of orientation that gives a sense of identity... born and bred in a Left-ruled State, it only heightened the ideo-bias since we studied, as part of the curriculum, two Constitutions of two erstwhile Communist countries, USSR and China... now of course, the same curricula has been revised to include the Swiss and French contitutions...
but most of us have forgotten the person behind what the West calls the fall of Communism... Mikhail Gorbachev... who with glasnost and perestroika, made way for the system to give rise to a new, undefined version of Statehood... this was way back in 1989, the first time i felt that history was being rewritten...
that time, it was redefinition of the Left... giving rise to new paradigms in international relations... Cold War, a major subject for us in International Relations, was deleted, since there was no Soviet Union... it was re-christened to Commonwealth of Independent States... so too small for the US to stoop and have war, cold or hot...
the subsequent 20 odd years have seen the unlimited rise of laissez faire... but what are we seeing now? bye bye Adam Smith, George Bush, in his last leg of Presidency, is doing what he might not have dreamt in his dreams -- nationalising major financial institutions, ones that formed pillars of the US economy...
so where is the scope for ideology? in a sense, this shows that nothing is really invincible... what would work is the question, since neither of the two have stood the test of time...
possibly a mix of the best of both... but who would bell the cat? who would suggest what is best? and who tests that, since it might only be a too costly experiment for which a running economy may suffer...
questions, questions... are there answers?
let me know, if you do...
