The most consequential NATO summit in decades is set to begin on Tuesday in Ankara, Turkey, where US President Donald Trump will engage with allies amid significant disagreements regarding Ukraine, the conflict in Iran, European defense expenditures, and commitments to nuclear deterrence. NATO leaders are expected to reinforce the 'ironclad' Article 5 collective defense commitment along with a €70 billion military assistance package for Ukraine. Analysts caution that the decisions made at this summit will have direct implications for the security landscape of every US state, particularly affecting the eight states that host vital NATO-related military infrastructure, which are at heightened strategic risk should the alliance weaken.
