Cameron is eager to launch strikes against Islamic State in Syria soon, believing that Britain cannot rely on other countries for security following the Paris attacks. His efforts to gain approval in the House of Commons on Wednesday have 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 the motion. Despite the opposition, Cameron's cabinet has agreed on extending air strikes to Syria as part of a broader strategy to combat ISIL. The debate in parliament is expected to be thorough and last 10-1/2 hours. When asked about the likelihood of securing a majority, he responded by saying, "Let's see what happens." Cameron is almost certain to receive parliamentary approval, particularly after Corbyn stated that he would allow his MPs to vote based on their own beliefs, rather than following the leader's guidance, which is a departure from the usual practice. Approximately 50 Labour MPs are expected to support the government, despite their leader's efforts to persuade them otherwise. Corbyn believed that Cameron's argument did not align with his party's principles. He emphasized the importance of each MP making their own decision on whether or not British troops should be involved in another Middle East conflict without a clear end goal. Many Britons are hesitant about getting involved in more expensive military operations in the Middle East, as previous interventions in Iraq, Libya, and Afghanistan did not bring stability and may have even contributed to the emergence of groups like Islamic State. British finance minister George Osborne estimated that extending air strikes into Syria would cost "low tens of millions of pounds." However, following the Paris attacks for which Islamic State claimed responsibility, some members of parliament who were initially against the air strikes now believe they are necessary to protect Britain from similar attacks. Defence Secretary Michael Fallon emphasized the "urgent need" for Britain to launch air strikes against Islamic State in Syria for the country's own security during discussions with MPs on Tuesday.
