US President Trump's April 2026 threats to withdraw from NATO over European allies' refusal to support operations tied to the Iran conflict and Strait of Hormuz reopening have heightened trader focus on alliance cohesion. These statements, describing NATO as a "paper tiger," follow earlier signals of US frustration with burden-sharing but face significant legal constraints under the 2024 NDAA, which requires two-thirds Senate consent or congressional action for any US exit. No member state has initiated formal withdrawal under Article 13 procedures. European capitals are advancing contingency planning for reduced US involvement while preparing for the July 2026 NATO summit in Türkiye. These dynamics underscore procedural and political barriers that limit near-term exits despite rhetorical tensions.
