Would the American public support a modern version of D-Day, an amphibious assault on a well-defended coastline to liberate foreign territory?

I ask this in light of the more than 4,000 Allied, mostly American, soldiers who died on June 6, 1944. They didn’t die to defend U.S. territory, they died to liberate others and end a global threat. Theirs, then, was a most exceptional sacrifice. Yet Americans back home supported their sacrifice for two reasons: they understood the moral necessity of victory, and they trusted their leaders to carry us to that cause.
