Drone Strikes in Yemen Accelerating Lately...But What If Anything Does It Signify?

Worth noting: There have been four reported drone strikes in Yemen over the past two weeks.  Long War Journal provides the details on the latest one here; LWJ's drone coverage in general is simply invaluable, particularly as mainstream media sources tend not to show much interest in particular strikes in Yemen.  Note that the recent spate of strikes follows a five-week period without any strikes earlier in the year.  This is a useful reminder to all of us on the outside to be careful when drawing inferences about the state of drone strike policy based on the apparent pace of things across relatively short periods.  It may be tempting to assume that the recent spurt (and the prior lull) somehow stems from changing policies, but I think it more likely that they simply reflect the unpredictable, fluctuating intersection between intelligence on the threat posed by specific persons and intelligence regarding their location and movements.
