Boeing 737 MAX 8

Wonder Why Everyone But The United States Is Banning The Boeing 737 MAX 8?

Plenty of conflicting opinions on the Boeing 737 MAX 8 and why virtually everyone in the world has grounded the plane. Why hasn’t the FAA made a move to ground the 737 MAX 8 or ban it from US airspace while other countries have? Is everyone looking at the same data? Are some countries overreacting or is the FAA not going far enough?
