Obama has no excuse for being unaware of what was going on. According to Human Rights Watch, several of Kyrgyzstan's best-known opposition leaders were jailed on politically inspired charges in the past year. Amid intensifying street demonstrations in March, opposition websites and independent radio stations were blocked or jammed, and the publication of three newspapers was suspended. Two prominent journalists were killed last year.
What happens next in vulnerable, impoverished Kyrgyzstan depends on whether its new and not-so-new leaders, representing in effect the country's third attempt at a post-Soviet fresh start, prove to be any more enlightened and trustworthy than their predecessors. It would certainly help if Russia and the US, and regional powers like China and Kazakhstan, do not try to exploit the power vacuum, confine themselves to constructive advice and assistance, and stop using the country as a Great Game playboard.
The US has had an historic, and almost pathological, pattern of looking the other way when a dictator (like Batista, the Shah, etc.,) was giving the US precisely what they wanted.
Then when the oppressed countries have had enough, and turn on their dictatorial leadership, the US always feigns shock, and wonders why it happened, and searches for other countries to blame.
Hopefully, if the current leadership here decides that that the Manas base has to shut down, the US is not going to do anything profoundly stupid, as Russia also has a base here in Kyrgyzstan, just 20 miles away from Manas.
The viability of Manas is not worth getting into a shooting war with Russia over; there are surely other alternatives.
