United Kingdom Prime Minister David Cameron said that it his country's “duty” to join the fight against the Islamic State group at a speech to the United Nations Security Council on Thursday.
“We are facing an evil against which the whole world must unite,” said Cameron. “And, as ever in the cause of freedom, democracy and justice, Britain will play its part.”
UK Parliament is due to vote on UK military intervention against IS in Iraq on Friday.
"There is no graver decision for our Parliament and our country. But protecting our national interest, security and the values for which we stand is why I will be supporting the motion this afternoon."
Cameron mentioned the country's last foray into the country as part of former U.S. president George W. Bush's war in Iraq, largely unpopular in the U.K., as not a legitimate reason for witholding support for the current military operation to fight IS.
"This is not 2003 but we should not use past mistakes as an excuse for inaction or indifference," said the prime minister.
Cameron ruled out the deployment of any combat troops in the fight against the Islamic State group.
