Of course Cruz knows 0bama will “mokusatsu” this proposal. (An appropriate word for today). There is no precedent for this in American history, so I don’t see it happening. Cruz can make political hay out of the fact that 0bama won’t come out and publicly defend his treaty, but other than that, this goes nowhere.
Of course Cruz knew Obama would refuse to debate. Either way, Obama loses. When in a war for the nation’s survival, good men use every means possible to win. Weasels like McConnell only pretend to fight.
