Somewhat low key. This article/clip is a reasonable summary.

Unfortuantely there is a joke in U.S. politics about "that depends upon what your definition of 'is,' is." -- meaning, on specific issues - is his objection to 'nukes,' in Iran and North Korea objections to nuke weapons or also objection to Iran's nuclear power program (which is legal and in accord with the UN IAEA).

Does he desire for reducing nukes and being honest with nukes include the "secret," nuclear weapons of Israel that somehow always fail to get mentioned.

Surprisingly firm, while committed to Israel's security he said the increase in Israel settlements was "illegitimate." - a rather firm statement and talked about the 1967 borders of Israel, and how Palestine needs a "contagious," free and real independent state.

But none of these things would seem acceptable to Israel at all, their "peace terms," clearly sounding like "we go on with aggression and expansion," statements.
