Will Great Britain Enter the Fight?

The Economist is an excellent source for straightforward, and often unbiased, global news. Yesterday, they posted this graphic from their magazine discussing England’s possibility of joining the fight against the Islamic State (IS) in Syria:   

Personally, I believe the most significant Pro’s from this list include numbers 4 and 6-8. Number 4 illustrates that the British Air Force is already fighting IS, and this vote would only expand their program. Numbers 6-8 all concern alliances that England with a neighbor (France), a comparable state (the United States), and the international community as a whole (the UN). It is in England’s best security interest to  honor these alliances to show their solidarity. If they do not respond now, and should one day need help from the international community after a Paris-like terrorist attack on London, it could prove difficult for them to receive any such help in the future.

The most significant Con’s, in my opinion, are numbers 1, 2, and 10. 1 and 2 point out the marginal benefit of England joining the fight might not be as useful beyond a show of solidarity, and could just pull resources away from their attacks in Iraq. Number 10 clearly shows what we learned in class of how democracies are often slower to go to war because they need public opinion before expanding or declaring any efforts. With a 50/50 split, and no dramatically convincing arguments on either side, this vote might end in a stalemate until further notice.

Do you believe this list is representative of decision making England’s Parliament needs to consider? Are there more you would add?
