I mean, you can't blame them. It's not like there was any recent precedent for a large thundering superpower to start a conflict (not a "war", of course)--under the assumption that a quick decapitation strike would end things in a few days--with an underestimated asymmetric adversary (one supported by a larger enemy) that responds with cheap drones and the like, resulting in an increasing quagmire, not to mention one resulting in the loss of valuable and irreplaceable airborne command-and-control aircraft during the conflict
