When did establishing a no fly zone in Libya become an all out war against Gadhafi arsenal?

Libya's air force was wiped out 2 - 3 weeks ago. Nato is and has been taking out Libyan tanks and shelling troops. How can they expect Gadhafi to comply with UN resolutions when those that impose the resolutions break the UN charter agreements? How can they expect anyone to believe this is not an all out war? And its Obama's fault!
