A coalition of European nations has agreed to share research and industrial experience to build an anti-ballistic missile defense system, moving away from its reliance on the U.S. as Ukraine struggles against Russia’s onslaught.

“We believe that the protection of Europe requires a global solution of integrated missile defense architecture to deter and defeat future missile threats,” according to a statement shared by the office of French President Emmanuel Macron, who hosted a meeting of Ukraine’s allies in Paris Monday.

“It will complement existing ballistic missile defense systems, including sovereign European solutions already acquired, or to be acquired by participating countries,” it said.
