DP World already operates the ports in China and Hong Hong that load the crap we buy from the ChiComs. If the UAE was infiltrated by jihadists bent on nuking the US, we would be unable to stop anyway, partially because of our insatiable appetite for cheap crap from China.
Sometimes it is really difficult to bring logic into an argument about "feelings."
Those monster cranes that unload nine million containers per year in American ports are what these companies manage. I wonder who paid for the massive cranes and the docks they stand on? I bet they were mostly done with private money, not taxpayer funded. We all reap the benefit of this world-wide transshipment of goods. The UAE is on our side - capitalist - not jihadist.
