"we should be able to treat this situation as urgently as things were handled in WWII." The US went into WW II because of Pearl Harbor. We didn't go in after Hitler had invaded most of Europe. We did send war supplies but didn't send troops. The urgency was when Japan committed a formal and very humiliating act of war. So that's probably not a great example of the US treating things with urgency. ISIS is odious, but given that we create the conditions for their existence due to previous rash military action, it would be wise to get a proper multilateral response with a full commitment and some actual hope to actually manage the aftermath with some chance of not having another horrifying group fill the power vacuum once we've stopped bombing. Realistically it's a hideous situation where if we grind ISIS into the dirt, we'll be elevating Iran's power in the region even more when we already got rid of Saddam's regime and replaced him with an Iranian puppet.
