The wording is perfectly clear. What are the chances of Congress ignoring something so unambiguous? They could no more ignore those words than they could ignore "shall not be infringed" in the Second Amendment.
detecting, (perhaps incorrectly) a bit of sarcasm in your reply, I would expect that the backlash would be enormous should Congress ignore 34 like-minded States whose citizens and legislators dedicated major time and effort to bring forth an application.
