The British Prime Minister David Cameron said on Thursday in a written statement to MPs that UK should join the air strikes against DAESH in Syria and cannot "subcontract its security to other countries."
"We do not have the luxury of being able to wait until the Syrian conflict is resolved before tackling ISIL (DAESH)," Cameron stated.
Cameron said in the House of Commons of the British Parliament that targeting terrorist camps in Syria and air strikes against DAESH would be in Britain's "national interest.”
Cameron rejected the claims over the decision for joining air strikes would make the UK a possible target for terror attacks.
He told MPs that DAESH already targeted Britain and now it was time to "take action."
British MPs are expected to vote soon on whether to be a part of the air strikes.
Cameron called MPs to support military action as he launches a "comprehensive strategy" to destroy DAESH.
"The question must now be whether extending the UK bombing from Iraq to Syria is likely to reduce, or increase that threat and whether it will counter, or spread, the terror campaign ISIS (DAESH) is waging in the Middle East” he said.
He underlined the UK could not abstain from struggling to the terror organization and it was "morally" intolerable to "outsource our security" to allies like France and the US.
He said, “If we won't act now, when our friend and ally France has been struck in this way, then our allies in the world can be forgiven for asking 'If not now, when?”
Since September 2014, Britain has been striking DAESH in Iraq as a member of the US-led coalition against the group. Cameron longs to widen the mission and attack DAESH in Syria, which would require parliamentary approval.
However, the possible air strikes have divided opinion in the opposition British Labour Party, led by Jeremy Corbyn, which is expected to vote against a military action in Syria.
Meanwhile, Cameron said in Paris on Monday in a joint press conference with the French prime minister that Britain had offered France a British airbase in Cyprus. France started the air strike in Syria in September 2015.
