Joe Biden’s ad team pounced on the moment that world leaders appeared to be mocking Donald Trump at the NATO summit in London. Just hours after video captured Canadian Prime Minister Justin Trudeau and others mocking the president, Biden released an ad saying:

“The world is laughing at President Trump. They see him for what he really is: dangerously incompetent and incapable of world leadership. We cannot give him four more years as commander in chief.”

The ad, which has already been viewed millions of times, ends by saying, “We need a leader the world respects.”

The one minute video is getting high praise.

Conservative columnist Matt Lewis wrote: “The key here isn’t just that this is a good ad. But the fact that Biden came out with this ad makes you believe he could actually wage a good campaign against Trump. That’s the key.”
