Yup. The people calling this "blackmail" aren't being fair either. Duh...if the situation was reversed we wouldn't be rushing to make deals with them in the future either.
You are absolutely right. This gives our country a bad reputation for all future deals, too--all it takes is some grandstanding idiotic legislators to squelch any legally crafted deals. Our word isn't worth much, if this deal is blocked by these weasels.
