If these two crash had happened in USA or Western Europe . Would the FAA have grounded the 737 right away . Or would they have waited before taking that decision

Turning that around a bit...

If it was a pair of Airbus aircraft (A320, A330, pick any you like) which suffered these two crashes, would the FAA have demanded the whole fleet grounded?

Interesting question as this particular case is suspected to be political/economical involved already.
