I'm not sure who, exactly, you're referring to, though I THINK you're referring to civilian government officials, rather than military personnel.
But I think there will always be assholes wanting to take over the world (insert Pinky and the Brain meme), and I, for one, don't want the U.S. to be caught with its metaphorical pants down when they try. Our current state of readiness keeps many of the assholes from even considering trying something now, but I have no doubt that they're just biding their time and watching for their chance.
I DO agree that there needs to be a cleansing of the government (one of the main reasons that I supported Trump over ALL the politicians, particularly the career politicians like Hillary) to get rid of all the influence-buying that goes on. One of the troubles is that the ones we need to have FIX the problem ARE the problem.
I also think the general public is too lazy to do what needs to be done, rather than think they're too stupid to know what needs to be done.
I'm going off on a tangent... GROOVY pain meds... Sorry.
