<h1>NATO Summit Faces Division as US Demands 5% Defense Spending While Spain Calls Proposal Unreasonable</h1> NATO leaders convened for a potentially divisive summit amid disagreements over defense spending targets. The US President demanded member countries spend 5% of GDP on defense, but Spain rejected this as 'unreasonable,' threatening consensus among all 32 members. European allies and Canada prioritized Ukraine discussions while expressing concern about potential shifts in US support. The summit was overshadowed by recent US military action against Iranian nuclear facilities. Despite NATO's collective security guarantee under Article 5, questions remained about American commitment to mutual defense obligations. Current defense spending shows 22 countries meeting the existing 2% GDP target, up from three countries a decade ago.
