The east opens up, poverty worldwide drops, yet we have our disaffected. Quite frankly it's not worth wondering why they think what they do any more. Nelson Ascher writing in EuroPundits, makes as clear an observation as any which could assemble the events of past 15 years among the western left into a pattern:
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.
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.
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. They may, outwardly, fight for some positive cause: save the whales, rescue the world from global heating and so on. But let’s not be deceived by this: they choose as their so-called positive causes only the ones that have both the potential of conferring some kind of innocent legitimacy on themselves and, much more important, that of doing most harm to their enemy, whether physically or to its image.
