Answer 1

In this particular case WW2 was a massive input, particularly in how it weakened the British empire both economically and politically. In WW1 the British empire was strongest but it began a decline after WW2, the fall of one empire and rise of another has effects like the change of reserve currency and more all which contributed. Of course America is also huge and geographically secure.
