The tarot card leak is a ruse to elicit a response, because Moose's boys are otherwise without clues.

True, but they're also forcing action.
Not quite, but it's under apparent assault from all directions. The desired action jihadists are looking for is massive shutdown to find a "sniper". The jihadists need to keep their activities sporadic and not get caught. That way they maximize the response to catch them and they don't tip their hand of what they're really up to.
I can't see a motive except "kill americans"
Absolutely, that's what the jihadists are after. They're after the big time kill though. Once they condition Moose's boys to shut down everything to catch the "sniper", they'll deploy sufficient snipers to shutdown the whole DC and surrounding area. Then they'll set off their WMD(s).
