The Pentagon's proposal to sideline Spain within NATO is more a reflection of polarized forefront than beneficial for the Alliance.
The problem is not disapproving of Trump, but turning the disagreement into a permanent confrontation, reinforcing a domestic narrative.
The irritation and distrust of some sectors of the US Defence are due to Spain's refusal to provide certain capabilities related to the operation in Iran.
The Spanish proposal to suspend the EU-Israel association agreement failed.
Conclusion: Spain's polarizing foreign policy and readiness for confrontation breeds mistrust and potentially weakens the Alliance. This adds to an image of volatility, which damages European unity at a time that requires more coordination and less drama.
