Islamic Fundamentalists tried to bring down the WTC in New York and there was no big US "Hammer cracking a nut" reaction fron the US' was there? Just the arrests of a few perpetrators and inciters.
In addition do you recall there was an attack that was thwarted against LAX around the start of the millenium? That resulted in a few individual arrests and convictions.
The bombing of US Embassies in Kenya and Tanzania resulted in a limited strike against OBL, his assets and his shelterers in Afghanistan.
The US wants a stable, peaceful Iraq built on solid foundations NOW so that it doesn't have to come back again and again and again to sort the mess out.
As for the recent attacks and arrests in the UK, they were unwelcome but long overdue. Personally I'd give any Police/Security services far greater powers regarding surveillance, stop and search, detention and shoot-to-kill but the more effective cure has to come from within the Muslim communities around the world, not just in the US,UK, Europe or the UAE otherwise if the attacks on Christians, Jews and Hindu communities by Islamic Fundamentalists continues then the backlash will harm mainly innocent Muslims and seriously disrupt those economies so heavily dependant upon expat skills, experience, expertise and labour.
Patience and tolerance are finite commodities.
