ISIS competes and overlaps with AQ, other jihadi groups and the Moslem Brotherhood for young recruits in Bangladesh and elsewhere, in messaging and for operational sustenance, as well as to demonstrate reach, at any given time now, in any given space, it seems to me.
Though their ideology, ideologues and leaders are increasingly defunct or laid bare, it seems, the business model of sustaining their causes always needs new cannon fodder, young recruits.
I think the age of the attacker may be an indication of a broader support network staying as distant as possible.
Omar Mateen and the flake who failed in Chelsea and on the Jersey shore were married, this creep is younger, maybe no wife and kids?
Thus, what happened 2015 when the taxi lic. expired? Is that connected to distancing?
This incident, whether there's the intel to consider links or not, is pepping their current and for new recruits, whatever peripheral issues at the time. They may be switching it up from attacks that cause widespread condemnation, retaliation and fortification against them to smaller scale very soft target attacks here and in Europe because they are building capacity, network and creds, possibly.
Poking to see what's on the radar or not too, maybe?
As such, Oceanblueeyes, I feel the same as you and you're right. Thank goodness so few were hurt.
