(Bloomberg) — JPMorgan Chase & Co. (JPM) Chief Executive Officer Jamie Dimon called out slow bureaucracy in Europe in a warning that a “weak” continent poses a major economic risk to the US.

“Europe has a real problem,” Dimon said Saturday at the Reagan National Defense Forum. “They do some wonderful things on their safety nets. But they’ve driven business out, they’ve driven investment out, they’ve driven innovation out. It’s kind of coming back.”

While he praised some European leaders who he said were aware of the issues, he cautioned politics is “really hard.”

Dimon, leader of the biggest US bank, has long said that the risk of a fragmented Europe is among the major challenges facing the world. In his letter to shareholders released earlier this year, he said that Europe has “some serious issues to fix.”

On Saturday, he praised the creation of the euro and Europe’s push for peace. But he warned that a reduction in military efforts and challenges trying to reach agreement within the European Union are threatening the continent.

“If they fragment, then you can say that America first will not be around anymore,” Dimon said. “It will hurt us more than anybody else because they are a major ally in every single way, including common values, which are really important.”

He said the US should help.

“We need a long-term strategy to help them become strong,” Dimon said. “A weak Europe is bad for us.”

The administration of President Donald Trump issued a new national security strategy that directed US interests toward the Western Hemisphere and protection of the homeland while dismissing Europe as a continent headed toward “civilizational erasure.”

JPMorgan has been ramping up its push to spur more investments in the national defense sector. In October, the bank announced that it would funnel $1.5 trillion into industries that bolster US economic security and resiliency over the next 10 years — as much as $500 billion more than what it would’ve provided anyway.

Dimon said in the statement that it’s “painfully clear that the United States has allowed itself to become too reliant on unreliable sources of critical minerals, products and manufacturing.”

Investment banker Jay Horine oversees the effort, which Dimon called “100% commercial.” It will focus on four areas: supply chain and advanced manufacturing; defense and aerospace; energy independence and resilience; and frontier and strategic technologies.
