I would caution you about the connection in CDG -- especially going from Europe to the US. Flights to the US leave from a separate satellite terminal, and have separate and extra security. Dealing with both will take a lot of time. 45 minutes to an hour is the barest minimum if everything works perfectly. I would not want to schedule a CDG connection in this direction for less then 2 hours.
I've found the reverse connection (arriving from the US and connecting onward in Europe) to be quicker. But I would still try to schedule at least 1.5 hours to be safe.
