Aussie and U.S. Citizenship oaths

Somehow the differences in these two oaths talk about the differences in the nations.

1. Australia:

Officially called the "Pledge of Commitment":
From this time forward, under God,
I pledge my loyalty to Australia and its people,
whose democratic beliefs I share,
whose rights and liberties I respect, and
whose laws I will uphold and obey.
All new citizens have the choice of making the pledge with or without the words 'under God'.

2. United States:

I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty of whom or which I have heretofore been a subject or citizen; that I will support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I will bear arms on behalf of the United States when required by law; that I will perform noncombatant service in the armed forces of the United States when required by the law; that I will perform work of national importance under civilian direction when required by the law; and that I take this obligation freely without any mental reservation or purpose of evasion; so help me God.

Which country is more afraid? Why?
