There is no sufficient institutional check on presidential nuclear authority, and no fast-track way to set up some sort of emergency restraint on Trump.

They are deliberate, substantive attacks on the rule of law, truth in political discourse, and Americans' rights, freedoms, and values.

Nature doesn't do subpoenas: it does tornadoes, floods, wildfires and droughts. No leader can stonewall it.

Suddenly, Cold War nuclear threats the treaty had long defused are coming back.

Putin and Trump have the capacity and responsibility to cooperate to make sure we are not humanity's last generation.
