at least Woodrow Wilson did immediately after the war and it was headline news all over the world and he received universal praise for the visit. Harry Truman and Dwight Eisenhower and Jack Kennedy visited cemetaries of both WW l and WW ll (on some of the visits there was driving rain). Ronald Reagan made a much heralded visit to WW ll sites on the 40th anniversary of the end of the war and Bill Clinton did the same on the 50th anniversary of the Normandy Invasion!! ALL of these visits and others had close and heavy coverage by ALL the media of ALL political stripes that were available at the time they occured!!
Fine if you support Trump's agenda go for it, knock your self out, but face it, as a decent human being worthy of any respect from anybody Trump is an absolute and abject failure by any measure possible!!
