Sadly, I sincerely believe that the driving reason for the overwhelming public sentiment against the UAE ports' deal is summed up here:
This racist propaganda, unfortunately, sums it up. It is s really depressing that Democratic and Republican politicians alike caved to (or worse, played to) a largely uneducated-as-to-basic-facts public's collective opinion rather than legitimately address (and maybe even attempt to educate about) the true merits.
The geopolitical fallout from this particular debacle will be significant, but not overwhelming. Of more concern to me is that I don't like what it says about our country generally.
