The results of the test should be understood in context of what was being tested. From the article: "Kadish acknowledged that the test, involving just one dummy warhead and one decoy, falls far short of simulating a real attack, which could conceivably involve multiple warheads and dozens of balloon decoys. But Kadish said that the test, although basic, is "operationally realistic in the sense that we've got these things in flight" and the kill vehicle must discriminate between them. Tom Collina, director of global security for the Union of Concerned Scientists, called the test "rudimentary" as a simulation of real threat conditions and questioned whether it really tests the kill vehicle's ability to discriminate between objects. The kill vehicle's computers, Collina said, have been programmed in advance with the infrared signatures of both the dummy warhead and the decoy – signatures it would not know in a real attack."
