If an asteroid is approaching earth, can NASA directly use its defense technique and destroy it or does it have to wait for a US government order,or wait for the whole world to take a decision with agencies like the UN?

Thank you for the response! Hope things doesn't get out of hands between governments like they always do. Just imagine if the space industry had all the budget allocated for wars and armies, we could do miracles! Well, until we start mining ressources from out there i'll keep dreaming.
