Al-Qaeda / US Army / ISIS in January 2016
http://stats.grok.se/en/201601/Al-Qaeda (~ 3k / day)
http://stats.grok.se/en/201601/United%20States%20Army# (~ 2.5k / day)
http://stats.grok.se/en/201601/Islamic%20State%20of%20Iraq%2... ( ~15k / day)
Al-Qaeda / US Army / ISIS in May 2013 (before Snowden's revelations & before ISIS/ISIL was known in the West[0])
http://stats.grok.se/en/201601/Al-Qaeda (~ 5.8k / day)
http://stats.grok.se/en/201601/United%20States%20Army# (~ 3.5k / day)
My conclusion, traffic is probably changing due to what is in the news rather than anything else. If the US Army is sent in to invade another country, their wikipedia page will be back on top.
ISIS was way higher last year, average about 25k/day in the middle of 2015, but the news media are tiring of them and they are also fading away.
That said, I was about to send a completely legit email yesterday that had the keywords "pipe bomb", "suicide vest", "IED", "Al-Qaeda" and "Mali" in it (a friend just lost two of his men in Mali), but I decided to self-censor for the benefit of the recipient rather than myself.
[0] ISIS was technically announced at the end of April, but they were not well known and the page was just a stub. It fell below threshold for collecting page view stats.
