American police kill more Americans than do terrorists. I'd call that an active and believable threat:

So when will the war on police start?
The June 2016 incident, the "Pulse" nightclub mass shooting, is a good case in point. The person involved wasn't "sent" to the US, he was a US-born national living in the US who'd never visited the middle East. He seems to have been radicalised by speech in the same way that other mass shooters were.
During his calls to 911 he said directly that the US bombing campaigns in the Middle East led to his mass shooting. He seems to be a direct example of how backwards US policy is.
Could that money not be spent better elsewhere to prevent other types of deaths? I think the U.S. and American politicians accept increases in budgets to the military so easily, that they don't even think about whether or not those resources are used effectively anymore.
It's hard to wage terrorist activities when you're fighting a literal multi-sided war.
We all know the answer to that one: we'd all be living under "amateur" Taliban, Mafias and worse anywhere near any large city, with constant public executions for "sacrilege" and for "competing" with the Mafia, and for ... There would be no international (or generally non-private) flights, and so on.
"Oh hey, yeah, sorry that a terrorist group armed someone to shoot up a gay nightclub, we feel real bad about that, but we need at least a hundred more people killed before we can do anything."
That's the usual response to white mass shooters in the US, yes. Especially in response to discussions of gun control.
Active and believable threats directed at the US, including sending resources and fighters to actively engage the US. It'd be great if we could give just give Iraq a ring and ask them to go shove a boot up these folks other-sides, but since they're massively losing cities and land to these warlords, they're not really in a place to handle the situation themselves. Something about a terrorist group taking large swathes of your land, borderline enslaving your people into forced labor and selling the pretty ones as "wives" to be raped endlessly kind of makes it hard to function as a normal country.
