Joe Lieberman wants some, particularly regarding any nuclear weapons agreement with Iran.

The only way to assure that [bipartisan unity] is for President Biden to submit an agreement with Iran to the Senate as a treaty, needing 67 votes to be ratified. That would require support from members of both political parties. It would bring Washington, for a moment, back to bipartisanship in foreign policy.

And

Achieving an agreement with Iran that could get 67 votes in the Senate wouldn’t be easy, but it is worth the effort. It would restore the longtime bipartisan consensus in Washington about Iran….

What is it that Lieberman wants here–bipartisanship, which is a worthy step to a lasting worthy agreement?

Or a permissive path for Iran to obtain nuclear weapons, which it then will use to destroy Israel, to sell to terrorists for attacks on Europe and the US, and to use itself around the world?b

An agreement that facilitates Iran getting nuclear weapons is not a worthy one.
