Actually, It's ridiculously easy to simply ship dormant AI into the country in boxes, have them establish operational state once here and have them sow the havoc you are looking to create.
Homeland c&c facilitates are certainly defended from terrorist actions, but less so from 20-30 kamikaze drones launched from within the victim country.
When you fight someone, the idea is to use their strength against them - the strength of the west is economic trade. All the security measures in the world won't stop fed ex. And if they do, well, in a way you've already won.
Drone defense is indeed a hot thing right now but it's not fundamentally different from protecting yourself from any other new type of threat. There's measures and there's countermeasures (http://petapixel.com/2015/07/23/anti-drone-systems-are-start...). At the point of (strong, general) AI though all bets are off the table.
Warfare is becoming more and more asymmetric and nuanced, that for sure. I'd posit some form of media training enabling one to be less vulnerable to say https://en.wikipedia.org/wiki/Information_warfare would do more good than rifles and bullets at home though.
Terror targets are basically useless though in a real conflict. A determined foe will simply ignore them.
My point is that for some shipping fees, you have a real, realistic and effective way of substantially reducing your enemy's ability to fight the war you are engaged in.
That's a real vulnerability that can be exploited.
