"The question was: Can YOU (i.e. you, REB, Robert E. Blier Esq., you) come up with 2 or 3 things that Bush flipped on. "

I could probably guess some that you would call a flip. Like steel tariffs. The problem is that anyone who is against tariffs in general is mainly worried about the long term effects of these laws. For instance, a true blue "Free Trader" wouldn't normally be opposed to govt taking action to prevent another govt support of illegal product dumping. I would say there are things about the steel tariffs but calling it a flip isn't accurate. And if anything it's another example of him sticking to his guns- by making WTO rule against them, it could seen as a step towards getting a level playing field.
And if the WTO didn't take strong enough action, and didn't act within a short time period, the president might have continued the tariffs. The main problem is the long standing tariffs by other countries and the unwillingness of WTO to take action.
