I disagree, for the same reason the US doesn't send an SM-6 up to greet every plane without an IFF turned on. It's an expensive exercise in endangering human lives, not a valiant defense of homeland security. Understanding the battlespace is a crucial part of modern warfare and soldiers aren't going to blind-fire on a weird drone unless it presents an immediate, credible threat.
Take the AIM-120s off your F-16 and put a FLIR pod on it, track the drones to wherever they land. Record the platform, dazzle it if it's got cameras or EO sensors, and send a few decoys out if you want to bait it into revealing last-resort defenses against a JDAM-like weapon. Then, you destroy it. Hell, if it's an unmanned naval platform you could also just send a couple Marines out in a Chinook to lift it to the Pentagon. America's weapons are nice, but we can do a lot more than just blow stuff up.
