Is Blair exaggerating the threat of terrorism?

Simon Jenkins has been indulging in his favorite sport of Blair-bashing again.

"The west is ruled by a generation of leaders with no experience of war or its threat. Blair and his team cannot recall the aftermath of the second world war, and in the cold war they rushed to join CND. They were distant from those real global horrors. Yet now in power they seem to crave an enemy of equivalent monstrosity. Modern government has a big hole in its ego, yearning to be filled by something called a "threat to security".

After 1990 many hoped that an age of stable peace might dawn. Rich nations might disarm and combine to help the poor, advancing the cause of global responsibility. Instead two of history's most internationalist states, America and Britain, have returned to the trough of conflict, chasing a chimera of "world terrorism", and at ludicrous expense. They have brought death and destruction to a part of the globe that posed no strategic threat. Now one of them, Tony Blair, stands in a patch of desert to claim that "world security in the 21st century" depends on which warlord controls it. Was anything so demented?"
