Not trying to stir up the whole political mess thing, but that was a different time and different circumstances. The threat was real and fairly clear-cut. Today the threat is veiled and works like the death of a thousand cuts - no individual one will kill you but put them all together and you are dead.
We are still safe from a concerted invasion, but vulnerable to individual hit-and-run attacks. There's no nation-state and its army to go after and defeat. Point out the real head of the real snake and then chop it off. Till then, keep your head on a swivel.
