In addition, the letter stated that Sweden signing the nuclear ban would close the option of joining NATO in the future, according to Dagens Nyheterin.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Swedish paper also cited a source raising fears that signing the nuclear agreement could impact defense industrial cooperation between Sweden and the U.S., including programs being worked on by Saab. Although not mentioned specifically, Saab is teamed with Boeing on a design for the U.S. Air Force\u2019s <a href=\"https:\/\/www.defensenews.com\/air\/2017\/05\/09\/swedish-air-force-interested-in-boeing-saab-trainer-jet-but-probably-not-other-t-x-options\/\">next-generation trainer aircraft<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pentagon spokesman Johnny Michael declined to comment on the letter itself, but said the U.S. \u201cdoes have serious concerns with the Nuclear Weapons Ban Treaty, and strongly discourages states from signing or ratifying\u201d as it contains provisions that \u201ccould potentially affect our ability to cooperate with parties to the treaty on issues of mutual interest. It also undermines the Non-Proliferation Treaty (NPT) regime.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, the U.S. \u201cvalues its defense relationship with Sweden,\u201d Michael added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">One hundred twenty-two countries agreed to endorse the treaty against nuclear weapons at the United Nations, which is up for a formal vote Sept. 20. Sweden was one of the nations that endorsed the treaty, and Foreign Minister Margot Wallstr\u00f6m has previously stated Sweden intends to officially sign on. Hultqvist, for his part, is reportedly against signing the document.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The U.S. is a vocal critic of the nuclear weapons ban, due to its longstanding policy of nuclear deterrence, but Mattis reportedly threatening cooperation between the two nations over Sweden\u2019s decision to sign the treaty surprised Jim Townsend, who spent eight years as deputy assistant secretary of defense for European and NATO policy and is now with the think tank Center for a New American Security.<\/p>\n\n\n\t<aside class=\"smg-interstitial-link wp-block-smg-interstitial-link\">\n\t\t<a href=\"https:\/\/one.sightlinemg.com\/defensenews\/pentagon\/2017\/05\/31\/interview-swedish-minister-of-defence-peter-hultqvist\/\" class=\"smg-interstitial-link__inner\">\n\t\t\t\t\t\t\t<div class=\"smg-interstitial-link__media\">\n\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"207\" src=\"https:\/\/one.sightlinemg.com\/wp-content\/uploads\/2026\/08\/635889763608794557-peter-hultqvistjpg.jpg?w=300\" class=\"smg-interstitial-link__image wp-post-image\" alt=\"\" \/>\t\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"smg-interstitial-link__content\">\n\t\t\t\t<span class=\"smg-interstitial-link__kicker\">Related<\/span>\n\t\t\t\t<h3 class=\"smg-interstitial-link__title\">Interview: Swedish Minister of Defence Peter Hultqvist<\/h3>\n\t\t\t\t\t\t\t\t\t<p class=\"smg-interstitial-link__excerpt\">Sweden\u2019s minister of defense spoke with Defense News while in Washington for his first meeting with officials from the Trump administration.<\/p>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/a>\n\t<\/aside>\n\t\n\n\n<p class=\"wp-block-paragraph\">\u201cYou don\u2019t use a threat to the bilateral relationship lightly; the impact on your own national security from actually using the leverage if you don\u2019t get your way can be damaging. The cause had better be worth the risk,\u201d Townsend said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Townsend said it was not surprising the U.S. would push an ally on not signing the treaty, and he noted his office had expressed similar sentiments in the past. But adding a threat, as this letter reportedly did, strikes him as misguided.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThey are a close friend in a dangerous neighborhood, and so threatening that important relationship lacks some credibility. Do the Swedes really think we would downgrade our relationship to punish them for signing a nuclear ban treaty?\u201d Townsend said. \u201cHowever, if Sweden did join NATO, they would have to reverse their anti-nuke stance because NATO is a nuclear alliance and so Sweden as a NATO member would participate in the nuclear planning as well.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Hultqvist, who is still under the threat of a <a href=\"https:\/\/www.defensenews.com\/global\/europe\/2017\/07\/28\/swedens-defense-minister-faces-vote-of-no-confidence\/\">no-confidence vote<\/a> in Sweden over a security breach resulting from the Transport Agency\u2019s outsourcing of an information technology database contract to IBM in 2015, told Defense News in a May interview that he was confident relations between his office and the Pentagon would remain strong under the Trump administration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cI have no signals that anything has changed between the United States and Sweden. I think we have the same position we have had with all administrations,\u201d he said May 17. \u201cSo I think there is stability in our relations. I am looking forward to discussing with him how to move forward and what we are going to do in the future.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>U.S. Secretary of Defense Jim
