Do As I Say, Not As I do.

Take one from the Bush Admin, don't do a half-assed job when you don't have to do one at all:
“These are treaty obligations, and everyone is expected to live up to treaty obligations,” [Rice] said.

US pulls out of Kyoto Protocol
US pulls out of Rome Statute
US pulls out of Antiballistic Missile Treaty of 1972

I guess if you don't feel like living up to them then you should just pull out...
