On Wednesday, Britain's House of Commons will debate whether to give Prime Minister David Cameron the authority to conduct airstrikes against the Islamic State inside Syria. Parliament approved airstrikes against ISIS targets in Iraq but rejected expanding that to Syria in 2013. After the ISIS attack in Paris, Cameron is expected to win this vote, meaning Britain could join the U.S., Russia, France, and a handful of other countries dropping bombs on ISIS targets within a few days.
Labour leader Jeremy Corbyn is against the proposal, but his party is split, and Corbyn's aides say up to 90 Labour MPs will likely vote for the expanded airstrikes. With the Liberal Democrats and Democratic Unionist Party favoring Cameron's bid, the measure is expected to pass after the 10-hour debate.
