In essence, this proposal has no security value in the current situation. The invitation is mainly seen as an additional option for France's allies and partners in Europe in case the US no longer continues to maintain its commitment to ensuring security for these countries, that is, no longer laying a "nuclear bunker" to protect or narrowing, even completely withdrawing troops and weapons from Europe.
Therefore, as long as the US does not take such steps, Washington's European allies are unlikely to accept Mr. Macron's proposal, even though no country has publicly rejected it yet. Most countries do not want to offend the US, and although confidence in Washington's commitment has somewhat declined, they are still cautious about the initiative from France.
Their concerns are well-founded because Mr. Macron in this invitation proposal maintains a monopoly on the decision to use nuclear weapons, not allowing them to have any form or level of participation. Mr. Macron also only leads France for more than 1 year, so if "new policies are adopted", what will happen to France's allies and partners in Europe?
However, Mr. Macron delivered a "blow" to the US when affirming that France can replace the US in ensuring security for Europe, raising France's position to the level of the US. At the same time, he implicitly implied that US allies and partners in Europe are no longer completely confident in the US security commitments. Although the US may not be immediately worried, it is certainly inevitable to feel uncomfortable with this move by Macron.
Mr. Macron wants to "Europeanize" nuclear deterrence to build a central nuclear role and position in the common security structure of Europe in the future. This proposal strengthens the security autonomy trend that the EU is promoting and will further strain relations between France and the US.
