Let's be honest: You loved it last week as you watched Nikki Haley lay the smack to the UN for its ridiculous resolution against our recognition of Jerusalem as Israel's capital, and you really loved the implied threat to make the UN pay when it was time for the U.S. to cut the check for its 2018 contribution to the UN's operations.
But you also feared: It would be awful if we made this threat and then backed down, going ahead and giving the UN the same money we always do in order to "maintain our influence" or whatever. That's what the diplomatic/foreign policy establishment would suggest we have to do, after all. Rhetorically you drop the hint, but actually following through is too risky, so you never actually do that.
If we'd gone that route, it would have been like getting invited to your favorite restaurant for dinner, only to show up and find it's been shuttered by the health department. Dang. Bureaucrats ruin my life again!
