THEY CAN’T HELP BUT LOVE US: The Main Attraction at Vietnam’s New War Museum: Anyone Who Looks American: Children mob U.S. visitors for selfies and handshakes outside, while displays inside condemn Yankee ‘imperialists.’

David McCaskey visited the new war museum here to see the American planes, helicopters and tanks from the Vietnam War.

But the 33-year-old graduate student from Buffalo, N.Y., quickly realized those exhibits were playing second fiddle to the museum’s star attraction: David McCaskey.

As soon as he entered the gates, about 30 schoolchildren in identical tracksuits swarmed him. They wanted a photo. Then another group did. And another. After 20 minutes of smiling for more than 100 children, he put on a face mask and sunglasses and finally slipped away.

“It’s the closest I’ll ever get to being a celebrity,” McCaskey said.

The Vietnam War ended 50 years ago Wednesday when North Vietnamese tanks rolled through Saigon, capital of the U.S.-backed South Vietnam. Today, tourists visiting the land of their onetime enemy are discovering that Americans are by and large beloved here.

We can’t help being lovable. Also, they’re next door to an expansionist China and need allies.
