They deal with us because it’s in their interest

Defense Secretary Robert M. Gates:

The fact is, governments deal with the United States because it’s in their interest, not because they like us, not because they trust us, and not because they believe we can keep secrets. Many governments — some governments — deal with us because they fear us, some because they respect us, most because they need us. We are still essentially, as has been said before, the indispensable nation.

For the time being, anyway.
