Has the Iran conflict exposed a fundamental US-NATO mismatch?

Jamie Shea, Former NATO Deputy Assistant Secretary General for Emerging Security Challenges spoke to CGTN Europe, discussing the perceived misunderstanding between the US and NATO regarding military operations. He addressed NATO is a defensive alliance, not an instrument for the US to use for every military operation. The US has been critical of NATO, but NATO has met the US's requests since Trump's presidency. The US should treat NATO allies as real partners for a successful alliance. He suggested there is a possibility of a more self-reliant Europe and security architecture due to the shift in European responsibility, but it should be done gradually and as part of a transatlantic partnership.
