Author's analysis, as critical as he is of American presidents breaking their promises, is completely absent of analysis of what would happen if American presidents broke their promises to never allow Iran to develop a nuclear weapon. Never mind that JCPOA had a sunset clause that would allow Iran to resume nuclear enrichment to weapons-grade after the sunset clause.
The author's analysis pretty blatantly exposes reality: the West is losing because it does not have the political stomach to win. Instead of deciding that maybe society should try to develop that political stomach, instead of paying attention to a Trump who got elected in large part on mantras about how America was losing and it needed to start winning, no, Author says this was all a horrible idea and implicitly we should just sit back while our enemies progress along the road of putting nuclear weapons in the hands of terrorists.
