Cameron is eager to launch strikes against Islamic State in Syria soon, believing that Britain cannot rely on other countries for security after the Paris attacks. He is seeking approval from the House of Commons to avoid a repeat of a previous defeat in 2013, but this has caused further divisions within the Labour Party. Labour leader Jeremy Corbyn has criticized Cameron for rushing into war and urged Labour lawmakers to reconsider their support for military action in Syria. Cameron's cabinet has approved the motion to extend air strikes to Syria, as well as Iraq, where British warplanes have been targeting since last year. He emphasized that the debate in parliament would be thorough and last 10-1/2 hours. When asked about the likelihood of securing a majority, he responded by saying "Let's wait and see." Cameron is almost guaranteed to receive parliamentary approval after Corbyn announced that his members of parliament would be allowed to vote based on their conscience, a departure from the usual practice of leaders instructing MPs how to vote on important matters. Reports suggest that around 50 Labour MPs will support the government, despite their leader, an experienced anti-war activist, hoping to convince them otherwise. Corbyn stated that Cameron's argument did not meet the demands of his party, and urged every MP to make their own decision on whether British troops should be deployed in another Middle East conflict without a clear end goal. A lot of British people are cautious about getting involved in more expensive military operations in the Middle East, given that previous interventions in Iraq, Libya, and Afghanistan did not bring stability and may have contributed to the emergence of groups like Islamic State. Despite the British finance minister estimating the cost of extending air strikes into Syria to be in the "low tens of millions of pounds," some members of parliament who were initially against the idea now believe it is necessary to protect the country from attacks like the one in Paris. Defence Secretary Michael Fallon emphasized the need for Britain to launch air strikes against Islamic State in Syria during a meeting with MPs.
