It's become a joke - through gritted teeth - these days in EU circles, that whenever leaders meet, as they did these last two days in Cyprus, expecting to discuss practicalities such as the new EU budget, they get railroaded by yet another crisis.

There is the ongoing energy crisis provoked by the US-Israel war on Iran, and Russia's aggression in neighbouring Ukraine, now in its fourth year. On Friday morning, souring relations between Europe and the United States, along with a potentially devastating defense impact, reared its Medusa-like head. Again.

No worries, Spain's determined-to-appear calm prime minister, Pedro Sanchez, said to waiting journalists as he arrived at the leaders' summit. We are fulfilling our obligations toward NATO.

What did he feel compelled to say he wasn't fretting about?

An email, originating from the US Pentagon and first reported by Reuters, leaked suggesting measures for the US to punish allies it believed had failed to support the US-Israel campaign against Iran. The email indicated that the US could seek to suspend Spain from NATO over its stance.

There is actually no provision in the NATO treaties to expel a member country. Any action to bar Spain from filling key civilian or military roles in NATO, also alluded to in the email as possible punitive action, would need unanimous endorsement from all NATO members.

EU leaders at the Cyprus summit, who are also in NATO, leaped to Spain's defense. Dutch Prime Minister Rob Jetten said he wanted to be crystal clear that Spain was and would remain a full NATO member. He asserted that European countries were doing a great deal to strengthen NATO, beneficial also to America's interests.

A high-ranking German official remarked, Spain is a member of NATO. And I see no reason why that should change. Meanwhile, Italian Premier Giorgia Meloni, criticized the tensions as not at all positive. She noted that public opinion is shifting against Trump, leading her to take a stance distancing herself from him.

The leaked Pentagon email also suggested scrutiny of the UK for its claim to the Falkland Islands, indicating potential rifts within NATO.

While the ramifications of the email sparked widespread concern among European politicians, Sanchez dismissed it, stating, We do not work based on emails. We work with official documents and official positions taken, in this case, by the government of the United States.

As the summit progressed, discussions arose around the potential invocation of the EU’s mutual defense article—42.7—should NATO's Article 5 become ineffective with Trump in office
