Worldwide, maybe not, but that's apples and oranges when comparing the threat inside our borders. I'm just commenting on the propensity to discount homegrown ethno-nationalist/"patriot" terrorists, when the evidence suggests that it's a legitimate concern. Remember what the largest pre-9/11/01 terrorist attack in the US was.
Maybe? Really?
I'm not trying to diminish what happened. There needs to be attention paid by DHS but in totality that attention should be minimal compared to Islamic terrorism. We have been lucky to not have more attacks here. It's just luck though.
