Jeff Sachs on Putin's offer to end the war. Should be negotiate?

Sachs is a powerhouse on US foreign policy and heads Columbia's Ctr for Sustainable Development. His reaction to Putin recently putting forth a proposal to immediately end the war and sit down at the negotiating table:

• Putin's proposal is a very good start.

• Is it 100% ok? Of course not...but it's a reasonable place to start and an astute good-faith effort for both sides to negotiate an end to this madness.

• Predicably the US and Nato told him to go f-ck himself. We refuse to sit down and talk. We'd rather keep shipping weapons and let the meat grinder continue.

• Our government is beyond ridiculous. Do I find this offensive? No, that word isn't strong enough.

• We have no end game or plan other than indefinitely fighting a war we can't win.
