'Former UK Prime Minister Tony Blair has described radical Islam as the greatest threat facing the world today.' BBC News - Radical Islam is world's greatest threat - Tony Blair er, partly thanks to YOU tone. cheers for that. no, really. 'Mr Blair, who led Britain into war in Afghanistan and Iraq, denied that his own policies had fuelled radicalism.' so definitely not your fault for following that halfwit Bush on his little escapade in the middle east, eh? does his political acumen have no beginning??
