This required a lot more than 50. There was a lot of planning and execution on this. Maybe foreign agents could do it with 50? If they were supported by satellites and other tools to which these attackers likely did not have access. But foreign agents are operating in relatively large teams even for simple missions. I don't think with this level of coordination, and this number of targets, spread over this large a geographic area, any intelligence agency is going to send one guy/gal per target. It only works like that in Bourne and 007 movies.
