It is truly sad to see Ted Cruz go off on this tangent. He has abandoned his strict constructionist view--which I shared fully--by embracing the Bill Clinton foreign policy, as demonstrated in the Clinton/Blair escapade against Serbian unity, for the purpose of keeping NATO more relevant, and perhaps making it into the substitute for the "Atlantic Union" project against American sovereignty.
Cruz seemed to have been made of better stuff. His anti-Trump antics over the past month are a big disappointment. I hope that at some point, he will reconsider. It is one thing to contest an election; quite another to compromise your integrity & principles as a tactic.
“Cruz seemed to have been made of better stuff.”
Blind, desperate ambition can present itself in many ways.
