Looks like the most incompetent and closely surveilled "lone moron" yet.
The Jihadi cause in the US seems to be scraping the bottom of the barrel.
To an outsider like me, it does look like the threat from a real organization with state patronage may be the only serious threat. Everything else is just police work and dumb luck (or lack of it). Organizations that used to have state patronage may still have some serious capabilities, but without a sanctuary, a serious well planned attack seems hard to imagine.
And before anyone jumps on me, let me note that I think 9-11 plotters did indeed have a sanctuary and did have training and support from more than one state (including, for some of their helpers, from the US in the 1980s). No self-started group of wannabe jihadis could have done it then and none can do it now.
Of course, there may be a whole secret world of plotters out there about whom I am clueless. But from reading the news, doesnt this look like a fair summary?
