Makes sense for them to make a sensation out of anniversaries (as a reminder to the West.) I've heard of that possibility before. Whether it's true or not .. but definitely always a concern.
I think the USA has enough to concern about with recent years of tornadoes, storms, economic issues, without needing any of that kind of rubbish.
I'm sure the extremists don't really want the USA government to change their mind & decide to put heaps of money into ridding of the extremist groups as they had previously (if mainly or only an excuse for the oil.)
Glad to see you back crymomma.
