The part I would worry more about is the selective pressure for violent psychopaths and lack of pressure against them - especially the anonymity. If there was a psychopath soldier who enjoyed say shooting kids for laughs he would at least make himself a high priority target even without any court martial/appalling his fellows enough to let him get killed or doing so directly.
Unless the CIA is involved with the designs there is a small upside that the robot dogs probably wouldn't be capable of rape at least. That isn't an inappropriate joke - it is an honest assessment of their record and moral character.
For the US as a belligerent the biggest demoralizer is that they seldom pick winnable fights and instead pick expensive quagmires for political points. That they fail even with science fiction ubertech demoralizes them further as it makes it cleae the lions lead by donkeys were fortunate in comparison. That seems to serve as progressive national permanent damage to faith. In the case of actually exercising the draft opinions have leaned stronger towards "Immediate treason or defection is the better option over fighting for one who enslaves me." since the Vietnam War.
Of course causus beli fabrication and propaganda to play on fears have also progressed as techniques unfortunately.
