The idea of a "war on terror" is a "mistake", putting too much emphasis on military force, Foreign Secretary David Miliband has said.
Writing in the Guardian, Mr Miliband said the idea had unified disparate "terrorist groups" against the West.
He said the right response to the threat was to champion law and human rights - not subordinate it.
Mr Miliband is due to repeat the views in a speech later in Mumbai, India, the scene of attacks by gunmen last year.
Mr Miliband's warning comes five days before the end of US President George Bush's administration, which has led the so-called "war on terror".
The foreign secretary wrote that since 9/11 the phrase "war on terror" had "defined the terrain" when it came to tackling terrorism and that although it had merit, "ultimately, the notion is misleading and mistaken".
Here's the closer to Miliband's commentary in the Guardian:
We must respond to terrorism by championing the rule of law, not subordinating it, for it is the cornerstone of the democratic society. We must uphold our commitments to human rights and civil liberties at home and abroad. That is surely the lesson of Guantánamo and it is why we welcome President-elect Obama's commitment to close it.
The call for a "war on terror" was a call to arms, an attempt to build solidarity for a fight against a single shared enemy. But the foundation for solidarity between peoples and nations should be based not on who we are against, but on the idea of who we are and the values we share. Terrorists succeed when they render countries fearful and vindictive; when they sow division and animosity; when they force countries to respond with violence and repression. The best response is to refuse to be cowed.
