"Those whom the fall of the Berlin Wall had left orphans of a cause, spent the next decade plotting the containment of the US. It was a complex operation that involved the (in many cases state-sponsored) mushrooming of NGOs, Kyoto, the creation of the ICC, the salami tactics applied against America’s main strategic ally in the Middle-East, Israel, through the Trojan Horse of the Oslo agreements, the subversion of the sanctions against Iraq etc. I’m not as conspiratorially-minded as to think that all these efforts were in any way centralized or that they had some kind of master-plan behind them. It was above all the case of the spirit of the times converging, through many independent manifestations, towards a single goal. Nonetheless we can be sure that, after those manifestations reached a critical mass, there has been no lack of efforts to coordinate them.
And so, spontaneously up to a point, anti-Americanism became the alternative ideology that came to fill in the vacuum left by the failure of traditional, USSR-based communism and its Maoist or Trotskyite satellites. Before 1989, the global left had something to fight for: either the strengthening of the communist states or the correction of what they called their bureaucratic distortions. To fight for something is simultaneously to fight against whatever threatens it, and thus, the leftists were anti-Western and anti-Americans too, anti-capitalistic in short.
Now, whatever they wanted to defend or protect doesn’t exist anymore. They have only things to destroy, and all those things are personified in the US, in its very existence."
This may explain why Micheal Moore, Harry Reid, Nancy Pelosi, et al. have much critique and little alternative.
