Heck are you paying attention? This company taking over is a Dubai government run company, no difference. Now to answer your question, no, I would not like a government takeover of port operations foriegn or domestic, I would like to see a private American company takeover but if it had to be a government entity running i'd surely rather it be American.
Its like this, you don't invite a suspected child offender over to babysit your kids, the case is the same here. As far as i'm concerned we cannot possibly know who is our friends in the M.E. given the current situation, cannot possibly know who is and is not infiltrated by Al Qaeda and other terrorist groups, the risks FAR outweight any cloudy benefits there might be to this.
Err excuse me, my bad, its a U.A.E run company, Dubai being the big city there.
