On Thursday Clinton strode out after a rendition of “Stars and Stripes Forever,” which was a nice change after months and months and months of Katy Perry’s greatest hits. “Roar” seemed like a good idea when Clinton first opened her campaign, but then she got all those complaints about how she was doing too much roaring. About boring details. She managed to become a candidate who was simultaneously criticized for yelling and for putting people to sleep.

But that was before. On Thursday, standing in front of enough American flags to make it seem like Banner Day on the Home Shopping Network, Clinton took on Trump’s history when it came to foreign affairs. She was clear and forceful and occasionally funny.

“He says he has foreign policy experience because he ran the Miss Universe pageant in Russia,” she sniped. Her friends have moaned forever that her sense of humor doesn’t come across on stage. This week it emerged. And Trump did say the thing about Miss Universe.

Good as the speech was, it can’t be the end of the conversation. While Clinton’s experience as secretary of state is certainly a plus, her longtime hawkishness should be a minus. She needs to tell the country what she’s learned about the limits to American power, and if she isn’t forced to during this campaign, that’ll be one more thing we can hold against Donald Trump forever.

But you could see why this particular speech, which was really one large thought about her Republican opponent, was not going to be the venue where she parsed over her own record. Making the case against Trump as a wildly dangerous threat to American security is both easy and hard. It’s easy because he’s said so many crazy things and hard because he’s usually also said the exact opposite.
