European Union leaders on Thursday committed to working together to bolster the continent's defenses and to free up hundreds of billions of euros for security after U.S. President Donald Trump’s repeated warnings that he would cut them adrift to face the threat of Russia alone.

US President Donald Trump launched a scathing attack on European leaders during the high-stakes EU Summit in London, urging them to shift focus away from Russia. Slamming their priorities, Trump warned the EU against over-concern for Putin while accusing Europe of failing to address issues like crime and immigration.
