Why it’s hard to have much hope:

Rabid anti-Semitism coupled with an addiction to implausible conspiracy theories is a very strong predictor of national doom; Nazi Germany isn’t the only country to have followed these dark stars to the graveyard of history. Many liberal minded Americans (though loathing both anti-Semitism and chowderheaded conspiracy thinking themselves) don’t like to look this truth in the eye. It leads to some very uncomfortable reflections about the potential for democracy in many countries beyond Egypt, and casts a dark shadow over the prospects for the development of a stable and prosperous Palestinian state. It suggests that there are narrow limits on what we can expect from diplomacy with Iran.

There’s a lot of delusional thinking in the White House along these lines.
