Am I right in thinking that there is no actual obligation with this sentence?

(The speaker is an ordinary citizen.)

The government must act now if it is to be re-elected next spring.

How about here? Is there a case of actual obligation?

You must tell me how to get one of those.

"The government must act now if it is to be re-elected next spring."

Not unless the government acts will be re-elected.

A strain of obligation is implied, IMO

"You must tell me how to get one of those."

moral obligation
<Not unless the government acts will be re-elected.>

Sorry, but I don't understand that sentence.
