Notice that the article only inferred that McConnell was referring to terrorism specifically. Perhaps they anticipate domestic unrest (due to, among other things, egregious NSA spying, ironically), and don't want to tie their hands behind their backs in the fight against that. In which case, a good time to do it, is whenever they decide to stop the spying and the impoverishment to destitution of literally everyone save for the rounding error of a demographic that constitutes the ruling and elite classes, et cetera. So, never.
