The US needs to know what will happen if an anti-American sheik takes over Dubai. And that could easily happen.
What will we do then? Where does that leave our Ports?
Dubai is the most liberal of the Emirates, the others are much more ... shall we say, not. Let's do the deal right. Neither side is desperate.
The same thing happens to the ports that happened to German-owned properties in WW2
Then put it in the deal. That would make it better for me.
Assuming it's not already too late.
