Why can't we all just get along?

There very well may be a downside to John J. Miller's argument that

...if France threatens to undermine American interests with its Security Council veto, we should call its bluff, pointing out that such behavior merely weakens the institution that is the prime source of France's undeserved prestige.

At the same time, I also agree with Antoine Audouard that the US media is excessively anti-French. However, he might have mentioned that the French media are pretty anti-American. Of course, there's a lot of bad feeling all around. Just take domestic American politics. Is the vitriol (on all sides) really necessary?
