I think this is pretty obvious and even mentioned this is a previous comment a few weeks ago. The US government has been saying that crypto is funding terrorism and money laundering. If you can’t read the writing on the wall then that’s your fault.
Even 9/11 is estimated to have cost the attackers only about $400K.
What costs is setting up an full-sized army, like ISIS.
* Fort Hood shootings
* 2009 SUV attack at UNC
* 2015 Chattanooga shooting
The DC sniper attacks might also qualify as Islamic terrorism. The perpetrators were Islamic, and their goal was terrorism, but it's not clear that the terrorism was actually perpetrated to further Islamism.
There will always be crazies. Although, crazies who can shop at a "Guns Galore" store cause more trouble than unarmed crazies.
