david, yes. It is an amazing thing about Trump-haters how myopic they are when given the facts. He didn't see active service in Vietnam, true, but neither did Bush, Clinton nor Obama, though he gets scoffed at. The testimonies by the above veterans seem to show why Trump feels as he does about this professional war-hero.
As the other link shows, he has for more than thirty years supported financially and with his time the war veterans, but what he gets from the above is "Out of a sense of guilt, perhaps?" and reference to simple-minded cartoon (for the simple-minded?) calling him a 'zero'.
