I also take it by the term "shortcut" that you are infering that an FAA CPL/IR is inferior to a JAA one
This is obviously a touchy subject. I have both FAA and CAA tickets and I don't have to imply anything. If you want to go down that route, it is a fact though that the Ground Exams for the FAA CPL are much easier than their JAA counterparts, and it is also a fact that the flight test is easier.
Unless you want a career in instructing or low grade P2 roles, it is also a fact that in the current market, you would require an FAA ATP to secure a career in aviation, even in the US. The FAA ATP flight test, for which there is no equivalent in JAA world is very very tough. I'd say that FAA starts easier than JAA and gets harder at the end. I don't think many would disagree fundamentally.
Humour me by not picking fights. You have requested and received a lot of useful information over your various FAA threads in recent days. A reasonable proportion of that has come from me.
