PARIS (AP) — French President Emmanuel Macron on Friday advocated a more coordinated European Union defense strategy in which France, the bloc's only post-Brexit nuclear power, and its arsenal would hold a central role.

Addressing military officers graduating in Paris, Macron set out his country's nuclear strategy in a bid to show leadership one week after nuclear-armed Britain officially exited the EU.

Macron highlighted how France sees its nuclear weapons as a deterrent against attacks from belligerent foes, though he conceded France’s nuclear might is diminished after its military scaled down its arsenal to under 300 nuclear weapons.

But the speech aimed to project strength, as Macron refused to sign any treaty at this stage to further reduce the French arsenal, announced an increase in military spending and positioned himself as the driving force for a united EU — using France’s military clout to make his point. Macron also touted the French military’s role in spots such as Africa’s Sahel, where he has just pledged an additional 600 troops to fight extremists.

The central idea in the keynote speech, however, was that of a boosted Europe-wide role for the French nuclear arsenal in a more coordinated European defense policy.

Macron said it the strategy would prevent Europe “confining itself to a spectator role" in an environment dominated by Russia, the United States and China.

"Europeans must collectively realize that, in the absence of a legal framework, they could quickly find themselves exposed to the resumption of a conventional, even nuclear, arms race on their soil,” Macron warned.

His remarks come at a time when NATO allies, who would ordinarily look to the United States for help in a nuclear standoff, worry about Washington's retreat from the multilateral stage. This could create new tensions within NATO, where Macron ruffled feathers last year by saying the lack of U.S. leadership is causing the “brain death” of the military alliance.

Last year, Russia and the U.S. pulled out of the Intermediate Range Nuclear Forces (INF) treaty — dating from the era of the Soviet Union — and each blamed the other for its failure. Evoking the tearing-up of the INF treaty, Macron said he wanted the Europeans to propose their own “international arms control agenda together.”

President Donald Trump didn't mince words when talking about the French premier's comments about the NATO alliance.

Friday's speech was part of Macron’s long-running push for a stronger European defense, as U.S. President Donald Trump has pulled away from European allies and admonished them to pay more for their own protection.

Macron explained his vision as "an offer of dialogue" and "service" to Europeans to assert their autonomy “in defense and arms control.”

There was no immediate reaction from the EU commission on Macron’s proposals. A spokeswoman said the bloc’s executive arm first needs to assess details of his plan. There was also no immediate comment from NATO, which includes two other nuclear powers — the U.S. and Britain.
