BRUSSELS — Finland is looking to join NATO for no money down, and its first month free, by referring Sweden through the alliance’s refer-a-friend program.

Speaking at a joint news conference at NATO Headquarters, Finnish Prime Minister Sanna Marin begged Swedish counterpart Magdalena Andersson to sign up so Finland could get a free month of membership.

“Hey, Maggie — this is a great deal. One month free and they waive the membership fee. That’s a lot of money,” Marin said. “Please. Just join for a month and then quit. You don’t even have to do one training exercise or any Article 5 stuff. C’mon.”
