I found this piece pretty persuasive. Money quote:
"It is understandable that American politicians would want to seek clarifications, safeguards, and accountability on the DP World deal in honor of all those who were mercilessly murdered on that tragic September morning. But the best way to honor their memories is to use the Dubai deal as a model to build effective bridges to the Arab and Muslim world — as we did in Pakistan, Iraq, and Afghanistan — instead of erecting barriers that reveal America's paranoia and fear about some Islamist doomsday scenario no one can predict, all the while alienating the very people we need to help raise up the Muslim world's disaffected so they are not so desperate to tear us down."
Good sense from the Washington Post as well. I'd like that 45-day review. But I see no reason to oppose the deal in principle.
