Telegraph - The perpetrators of Thursday's atrocities are living in a fantasy world if they think the British people can be intimidated by terrorism, let alone converted to Islam.

The findings of YouGov's survey show they are equally deluded if they think they can drive a wedge either between Britain and the United States or between most Britons and their Muslim fellow countrymen.

The vast majority of YouGov's respondents are proud of London's emergency services and of the way ordinary Londoners responded to Thursday's bombings.

They have no intention of changing the way they live and work merely to satisfy the desires of a few fanatics.

Not surprisingly, people's willingness to see the authorities taking whatever steps are necessary to apprehend and, if need be, detain potential terrorists has risen sharply.

More than 80 per cent believe the threat is so serious that the authorities should act against suspected terrorists even if they have not committed any offence.

The survey also reveals increased support for identity cards. Compared with last week, support for ID cards has increased significantly, almost certainly as a result of the attacks. Even so, people by a wide margin remain unconvinced that the introduction of cards would help prevent terrorist acts.

Although most Britons do reckon that the London bombings were the work of Islamic extremists, most show no disposition to point the finger of blame at British Muslims as a whole. On the contrary, well over 80 per cent are convinced that the great majority of British Muslims are peaceful, law-abiding citizens who condemn the bombings like everyone else.

The response of Tony Blair and his ministers to the attacks has clearly boosted the standing of both. Early this year, twice as many people said they were dissatisfied with Mr Blair as Prime Minister as said the opposite. In the aftermath of Thursday's bombings, Mr Blair's approval rating has flipped from negative to positive for the first time in five years.

Moreover, the bombings have failed - despite Mr George Galloway's best efforts [see here - ed.] - to undermine support for the British presence in Iraq. The proportion wanting British troops brought home quickly has fallen and the proportion who now want Britain to retain its close ties with the US has risen. The section of the chart headed "Assessing performance" tells a story of which Britons can be proud.
