"loose talk"

[Ju]

Barack Obama has warned against "loose talk" of a war with Iran and insisted sanctions must be given time to prevent the country pursuing nuclear weapons.

What is the meaning of "loose talk" in the above sentence?

Thank you.

Careless, provocative, undiplomatic, etc

"Loose talk" certainly means all of these things, but I think the cited usage might also entail "unsanctioned" or "unofficial" or "premature".
