I want to know the answer to the following question:
When did Obama launch airstrikes on ISIS?
All the background I'm provided with is that "On 9 September 2014 President Obama said that he had the authority he needed to take action to destroy the militant group known as the Islamic State of Iraq and the Levant, citing the 2001 Authorization for Use of Military Force Against Terrorists, and thus did not require additional approval from Congress.". Is that enough to answer the question?
Answer: no
