Veni Vidi Ego Dubito
His McCain comment was personal not general against the military . I was drafted and served in VN as a Army medic. I don’t hold anything against anyone for not serving, even those that turned their backs and ran to Canada .During the Vietnam era, 9.7% of Trump's generation served *in* Vietnam alone (plus another 2.5% in wider Asia and many more in the wider military).
He avoided the draft which might have been common enough but then went on to show gross disrespect to those who *did* serve (his views on John McCain being a 'loser' for being caught as a pow, the canned veterans' cemetery visit for example) and, to cap it off, focussed his Memorial Day musings on himself rather than the deceased.
Trump vigorously supports the military as every American should, it is a necessary part of life. Witness the Ukraine.
I agree about his turning his Memorial Day address into political speech.
But thaf is part and parcel with DJT, guerrilla tactics against the evil traitorous Deep State .
