I agree with Frances' answer but would like to add a couple of points.
England has always had more faith in its TDs giving correct rulings than elsewhere. However, world opinion has swung everywhere towards giving the correct ruling. The idea of always ruling in one direction and letting Appeals Committees do their work for them was at its height in the 1980s especially in North America.
As to whether 2
is an LA the standard outside North America, Great Britain and one or two other places tends to be an action that at least one in four players of like ability would find. The old idea of whether the UI makes a bid easier or safer is no longer part of the Laws.
