Deepening Divisions

I praised Salon yesterday. That covers me for the quarter. Now I got to be snarky again. This is actually a good article, but the conclusions are off.
It starts off examining the record of Britain policing terror:

Since the attacks, there have been at least four more serious terror plots in that country, including the widely reported incident just weeks later when four suicide bombs failed to explode. In April 2006 alone, according to the Daily Telegraph, police were involved in 70 antiterrorism investigations, and officials said the pace was "accelerating." Of the more than 60 people facing trial on terrorism charges, two-thirds were arrested after the 2005 attacks.

Great. All to the good.
Then, the question is, are they simply better at capturing scary guys, or are there just more scary guys over there:

The difference in arrests in the United States and Britain appears to have much more to do with demographics than the relative skills of law enforcement. Most terrorism experts say the most insidious threats from terrorism now come not from organized terror organizations launching attacks that were hatched overseas, but from disenchanted Muslim extremists at home. And Muslim communities in the United States are generally more affluent and less dogmatic than those in Britain, which has a Muslim population of nearly 2 million. O'Hanlon described Muslim communities in Britain as "more cut off and more isolated" than in the United States.

Evil ole racist America is better at integrating people and making them affluent? No. Not possible? Is it? Evidently so.
Salon then derives these conclusions from those facts:

The cultural issues that create a higher threat level in Europe may fray the transatlantic alliance in the war on terror, as European countries, including the U.K., grow wary of supporting any American tactics that might inflame Muslim anger at home.

So, let me understand this. The US doesn't have a disaffected underclass and is actively trying to stop murderers abroad. European countries seem to growing their own terrorists internally, and rather than address that issue, they're going to stop supporting the US? Normally the word that would be used for this attitude is "appeasement," but in this case I think the more appropriate one is "surrender."
